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.
In this lecture we will look at data which are the time to an event, such as death or healing. The main problem with such data is that subjects are usually observed for differing lengths of time. We can estimate the proportion who are still free of the event at any time, using the Kaplan Meier survival curve method.We can do a test of significance between different groups using the logrank test and get an estimate of the difference in survival between two groups using the hazard ratio.e can estimate the proportion who are still free of the event at any time, using the Kaplan Meier survival curve method.
