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.
For example, in a clinical trial with survival time as the outcome, if the hazard ratio is 0.5 comparing participants on a treatment to those on placebo, this suggests a 50% reduction in the hazard (risk of failure assuming the person survived to a certain point) in the treatment group as compared to the placebo.hese estimates of survival probabilities at specific times and the median survival time are point estimates and should be interpreted as such. There are formulas to produce standard errors and confidence interval estimates of survival probabilities that can be generated with many statistical computing packages.
