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.
Median Survival Time. This is the survival time at which the cumulative survival function is equal to 0.5. Other percentiles (25th and 75th percentile) of the cumulative survival function can be computed accordingly.Note that the 50th percentile (median) for the cumulative survival function is usually not the same as the point in time up to which 50% of the sample survived.edian Survival Time. This is the survival time at which the cumulative survival function is equal to 0.5. Other percentiles (25th and 75th percentile) of the cumulative survival function can be computed accordingly.
