Can the life distribution platform be used to calculate confidence intervals for custom percentiles assuming a distribution? It looks like the custom estimation option under "parametric estimate" within the life distribution platform allows for this. The fit distribution platform only allows for distribution free and smoothed estimates to the best of my knowledge not distribution specific estimates.
You can use the Life Distribution Platform to calculate confidence intervals for custom quantiles by each available distribution. Both Wald and Maximum Likelihood confidence estimates are generated. Select the red triangle option next to the distribution you have fit. Choose Custom Estimation. You can then choose Estimate Probability or Estimate Quantile. Use the + option to build a table of the custom estimates you are interested in.
