The problem statement is I want to be able to compare 2 populations' survival and give a confidence interval around the point estimate. JMP can plot a simultaneous or pairwise confidence interval around any given population, but cannot give a confidence interval around the difference. Therefore, I suggest to everyone in my company to use R or python to do survival analysis, because the point of comparing survival is to quantify the difference, and the uncertainty in the difference.
RMST is one way to compare survival across 2 populations and derive confidence intervals.

I suggest JMP impelement RMST.
