Plotting confidence intervals in parametric survival analysis(Weibull)
Mar 11, 2014 11:20 AM(1181 views)
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?
