Hi all,

I am doing a parametric survival analyses (Weibull), and I would like to plot a curve similar to the one below. I could plot the mean (blue trace below), as JMP gave me the formula for it, but I am not able to plot the confidence intervals as JMP wont give the formula. However I could see the plot (mean and CIs) in the "profiler" of the platform.

The formula to compute row wise mean quantiles that JMP gave me is below, where : Probability is a column with numbers from 0.001 to 1 by 0.001. Delta, Intercept and AGE are regression predictions. Is it possible to compute row wise confidence intervals using the same formula, knowing standard errors?

Weibull Quantile( : Probability, 1 / Delta, Exp(Intercept+ AGE* :age )

Any suggestions are appreciated.

Thanks in advance.
