Kaplan-Meier curves and log-rank tests are most useful when the predictor variable is categorical (e.g., drug vs. placebo), or takes a small number of values (e.g., drug doses 0, 20, 50, and 100 mg/day) that can be treated as categorical. The log-rank test and KM curves don’t work easily with quantitative predictors such as gene expression, white blood count, or age. For quantitative predictor variables, an alternative method is Cox proportional hazards regression analysis. Cox PH models work also with categorical predictor variables, which are encoded as {0,1} indicator or dummy variables. The log-rank test is a special case of a Cox PH analysis, and can be performed using Cox PH software.

A recreational day hike could easily turn into a survival situation causing you to camp overnight in the wilderness. Take the wrong turn on the trail or forget to orient your map to the terrain and you might be walking the opposite direction in which you thought. It is important to always carry a shelter, fire striker or matches and something to carry water in, no matter how short a trip you have planned. BUDK has a large selection of everything you need for camping and survival needs!

You have a freedom to choose your own purpose, and this pressure to choose can be viewed also as burden. When you feel you must find your purpose, you can look at your mind from distance and be conscious about it.

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.[4]

• My next tip maybe common sense to some, but figured it’s still worth noting: for better maintenance of keeping balance, it’s best to keep heavier things on top and the lighter items at the bottom. What this will do is help you with stability while you are on the move. 

Keep your fire contained! Ensure that there is no combustible material near your fireplace and enclose it completely with rocks or a berm made of sand. Put your fire out with copious amounts of water: saturate it, so that there is no possibility of even the tiniest spark remaining. You should be able to touch the extinguished coals with your bare hand. It’s one thing to be lost in the woods, but quite another to be lost and surrounded by a forest fire caused by your own negligence.

Whether you’re working around the house, cutting rope for your campsite, splicing electrical wires in the garage, or slicing up vegetables, our small, but effective folding pocket knife will get the job done right.

she gives us her most important 
how-tos:

Don’t dally with the mask. During a loss of cabin pressure, the drop in oxygen can knock you unconscious in as little as 20 seconds. Listen to your flight attendants: Always secure your oxygen mask before helping others. You can’t help if you can’t breathe.

Now, there are three things needed to start a fire: fuel, oxygen and a spark. You have two of these in abundance in the wild. There is the almost unlimited amount of fuel in the form of twigs, branches, and dry leaves and there is oxygen all around. What you are missing is spark or heat. So, let’s see what you can do to make that spark or heat happen.
