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.
Conclusions. The dramatic difference in live-birth survival rates between 22 and 25 weeksâ gestational age (from 6% to 81%) confirms that with our current management practices 22 to 25 weeksâ GA is the threshold of viability.
