It would have cracked the iceberg open! It also would have  completely destroyed the bow of the ship causing a much more fast  sinking.    Uh...not quite. Icebergs ar â¦ e solid ice, and though the weight of  Titanic was considerable (46,000 tons), it was maybe a fifth of the  weight of the iceberg.
Means and Median for Survival time Kaplan-Meier procedure Since there is a lot of overlap in the confidence intervals, it is unlikely that there is much difference in the average survival time. If confidence intervals do not overlap between levels, differences in effect on time to event can be inferred.Event history analysis âTime series analysis When use survival analysis âResearch interest is about time-to-event and event is discrete occurrence.
The study will certainly record the survival time of each patient (measured from the time of the surgery). This really is the outcome of the study; survival time is the response variable. Now, each patient will get one of the two types of operations; this is a second variable. . .let's call it the procedure variable; it takes one of two possible values, Angioplasty and Bypass.
