The null hypothesis for a log-rank test is that the groups have the same survival. The expected number of subjects surviving at each time point in each is adjusted for the number of subjects at risk in the groups at each event time. The log-rank test determines if the observed number of events in each group is significantly different from the expected number. The formal test is based on a chi-squared statistic. When the log-rank statistic is large, it is evidence for a difference in the survival times between the groups. The log-rank statistic approximately has a chi-squared distribution with one degree of freedom, and the p-value is calculated using the chi-squared distribution.
I purchased a credit card knife for a few bucks at http://survivallife.com/credit-card-knife/. I signed up for NOTHING else. Immediately after purchase they give you all of these internet marketing type offers (upsells). I declined all of them. Afterwards I see that I’ve been billed some sort of lamplighter society scam membership. The lamplighter society is some membership type scam.
A cautionary note about that pool shock: it is extremely hazardous (once opened)…it’ll eat through metals and (some) plastics and should be kept from moisture because that is what ‘activates’ it…wear gloves (the right kind), get an MSDS (manufacturer’s safety data sheet) from the internet and store it AWAY from your food supplies. If there are curious little ones in the vicinity, make sure you keep it locked up.
Survival Power: Your fitness level to climb and descend and your ability to recognize and tie good anchor points relies solely on practice — without prior knowledge or practice, using a belay device to rappel is dangerous.
Forti continued, “In reality, a backpack full of camping gear is simply a large ‘survival kit’ designed for a comfortable and extended stay in the wilderness. A much smaller version of this might consist of a tobacco tin with relatively few items tightly packed in.”
MCarper/ShutterstockWhen a ring threatens to cut off circulation to a swelling finger, you have to get that tiny tourniquet off any way you can, says James Hubbard, MD, MPH, author of The Survival Doctor’s Complete Handbook: What to Do When Help Is Not on the Way. Before you buy a ring cutter or draft an apology letter to your beloved, check your bathroom cabinet for dental floss. That little spool of string just might be your salvation. What to do:
Rather than MRE’s, check out your local LDS/Mormon “Bishop’s Warehouse” for cans & Mylar bags of bulk and dehydrated foods. The cans are designed for 30+ year storage and the Mylar bags are perfect for hiking, camping, and survival. They are a lot cheaper than MRE’s. You can even buy some Mylar bags and make your own “meals in a bag” for even less money.
Why do we call it the ‘Survival Guide’? We’ve heard too many artists say they aren’t business-minded, yet understanding that you are a business is necessary to thrive in this industry. To thrive, you need to know how to survive in unfamiliar territory. Let’s admit, ‘being an artist’ and ‘savvy business’ are not strong associations. But it doesn’t have to be that way. We want to unpack all that it takes to create a solid business foundation, so we have created this workshop to give you the tools to not just survive, but thrive. Come ready to rack John’s brain with all of your pressing questions. He’s been at this for 16 years, and has built something pretty great – he’s ready to pass that on. Here is a small taste of what to expect.
Wilderness survival sometimes calls for being found — that includes in a time of collapse as well. Perhaps you’ve put together a camp in a remote location. Whatever circumstances take place where you’re now cooperating with other people for survival, tasks related to hunting, scouting, and scavenging can mean you have to split off from the group at times.
If you sleep downwind to the campfire, your whole shelter will soon start smelling like smoke and fire, and you don’t want that. Also, there is a chance that if the gusts are strong, a burning piece firewood can fly right into your shelter while you are asleep.
An alternative to building a single survival tree is to build many survival trees, where each tree is constructed using a sample of the data, and average the trees to predict survival. This is the method underlying the survival random forest models. Survival random forest analysis is available in the R package randomForestSRC.
Condoms also burn. A latex condom will light up instantly, making it perfect tinder for getting a fire going. And since they’re watertight by nature, they can also be used to safely carry dry tinder. In a pinch, you can use condoms as rope to tie up a tarpaulin for shelter or—seriously—even turn them into a slingshot to hunt small game. Yes, you can hunt wild animals with condoms.
It may also happen that subjects with a lifetime less than some threshold may not be observed at all: this is called truncation. Note that truncation is different from left censoring, since for a left censored datum, we know the subject exists, but for a truncated datum, we may be completely unaware of the subject. Truncation is also common. In a so-called delayed entry study, subjects are not observed at all until they have reached a certain age. For example, people may not be observed until they have reached the age to enter school. Any deceased subjects in the pre-school age group would be unknown. Left-truncated data are common in actuarial work for life insurance and pensions.
Find water: As the subjects of my stories know too well, you can last only about four days without water. To ward off dehydration, search for animals, birds (especially songbirds), insects (especially honeybees), and green vegetation, all of which can indicate that water is nearby. Rock crevices may also hold small caches of rainwater.
Back in 2015, I reviewed the original Kershaw Shuffle. I don’t normally review newer models because usually the differences are so slight (Paramilitary 2 vs Paramilitary 3 for example), but in the case of the Shuffle II, it might as well be a…
Three Piece Bamboo Bow: If you take a good close look at these photos you will be able to figure out how I made them, quite easy. All you need is a few different size [dry & dead] pieces of bamboo so the ends of the bamboo will fit snuggly one-inside-the-other and then attach some paracord as a bow string and you got yourself a three piece bamboo bow. To make sure the ends of the bamboo don’t crack and come apart, where they fit snuggly one-inside-the-other, lash some paracord securely around them.
• Double half hitch: Used to attach one end of a rope around an object. This is a useful knot for building a shelter. Tie a half hitch around your object, like a tree or pole, and follow it by a second in the same direction to make it a double. Pull tight to make secure.
ThinkGeek provides tools for the tactical advantage. Whether your idea of enjoying the outdoors is your own backyard or escaping off the grid, we have just the right supplies to help you prep for an emergency situation (zombie apocalypse) or a weekend spent enjoying your patio with neighbors.
I ordered that item on Dec. 6/16 and have order # 5FR74DEN from Survivallife.com and sent them multiple e-mails which they have answered a few but the 2 they have not bothered.So here they are listed below.
The survival function must be non-increasing: S(u) ≤ S(t) if u ≥ t. This property follows directly because T>u implies T>t. This reflects the notion that survival to a later age is only possible if all younger ages are attained. Given this property, the lifetime distribution function and event density (F and f below) are well-defined.
You certainly couldn’t accuse him of living life in half-measures anyway, but whether he’s being badass, ingenious or just disgustingly logical, he certainly knows how to get the job done. Here are some Bear Grylls survival tips that prove just that… We’re guessing you don’t fancy following all of them!
About Blog – Off Grid Survival is a preparedness & survival website that is dedicated to helping people become self-reliant and better prepared. It is an online resource for survival information. From wilderness and urban survival to emergency preparedness and off grid living, It provides you with the knowledge you need to survive in any situation.
Binoculars are often overlooked as an essential piece of survival gear. The fact is, you can survive without binoculars, just like early century Native Americans who lived off the land. Key difference though is that they knew the land — there’s a good chance you’re going to end up in a place that you don’t know very well, especially in a mountain range, vast desert, or national forest.
Survival Throwing Star-Knife: Here’s one for all you knife freaks & gurus. Ok, I know they make those metal throwing stars, but this baby can be used in multiple ways in a survival situation. As an individual hunting & throwing knive, a throwing star and as spear head when attached to a stick for hunting game or spearing fish. To make one of these all you have to do is buy a set of those cheapo metal throwing knives, drill a few holes, make a few groves on the handle(s) so when you go to wrap some paracord around it to attach it to a stick it will hold it in place and not slide off. And then add four (4) screws, washers and wing nuts to keep it together until you need to use it.
The kits provided for Soviet and Russian Cosmonauts are optimised for survival in the temperate and sub-arctic mountains, forests and grasslands in the east of the country. Soyuz spacecraft kits include food rations, water bottles, warm clothing, rope for making a shelter using the capsule’s parachute, fish hooks and miscellaneous other survival gear. A specially designed pistol, the TP-82, was provided to defend against predators such as wolves or bears. It was able to fire conventional bullets, shotgun cartridges and flares; the folding stock could be used as a shovel and it also had a fold-out machete.
We all experience hardships. Some people get through them with greater ease than others because of their attitude and choices. Their mindset propels them forward. They don’t let suffering run their lives and they work through the hard times, even when everything is falling down around them and they can’t seem to get a break.
Your list is pretty good and pretty comprehensive. However, it seems a bit all over the the map. Maybe some further breakdown of home/car/BOB would be in order. Right now, my home and car kits are good, but I’m browsing the web for ideas on more or better gear for my BOB. And as I’m browsing through your list I see…
blvdone/ShutterstockWhen a huge crowd hits a tight choke point, a scary thing happens: The crowd starts moving like a fluid, each person forced forward by the people behind, regardless of whether there’s anywhere to move. This occurred last September when a group of more than a million pilgrims reached a narrow street intersection in Mecca. Trapped between the force of people behind them and the wall of people in front of them, some 2,200 died from compressive asphyxiation, the air literally crushed from their lungs. It’s a terrible fate but one you can avoid. Here’s how.
Jingjits Photography/ShutterstockRemember this: When you’re as red as a beet, make yourself a salad. Freshly cut cucumber cools and soothes the skin, as does the starch from a grated potato or a spritz of apple cider vinegar. Your skin needs vitamins A and D to heal quickly—augment your produce regimen with lots of milk, and find a cool place to veg out. You can also try these sunburn home remedies.
No problem. In my case the teacher (Math & English, including grammar) was my grandfather. In my household “ain’t” was a four letter word, and improper verb tense was a minor crime. I have most of it ready to go except for some paragraph cleanup. Cut & paste from the original pdf, a little editing, a little Perl script for the tables, & viola. When complete I plan to send it to MD to do with what he wants. Perhaps a few of us can help turn it into a new improved & expanded edition.
In that time, I ordered some of the items they had to offer. I was disappointed that their stated 15 to 21 business days to deliver a purchased item was standard for them. It got a little better over time, but never got below 15 days.
This survival tool is called Rescue Me Balloon, a small, easy-to-carry emergency survival tool that places an SOS balloon 150 feet above a person in an survival situation and illuminates an SOS signal using an LED light. The rescue me balloon will s
If you need the help of a compass but you don’t have one, you can use an analog watch to do that. Point the hour (short) hand at the sun and draw two imaginary lines between it and the 12 o’clock point. You will create an angle between the two lines. Draw an imaginary straight line bisecting the angle. The line point away from the sun is north, because the sun always goes to set in the west direction.
