For each failure-time distribution, generate 1,000 right-censored samples, fit the appropriate model, and get point and interval estimates for A (in the exponential model) or for A and y (for the Weibull and log-logistic models). Are the point es- timates close to the true values? Do the 95% confidence intervals contain the true values? In each part, use an exponential(1) distribution as the censoring distribu- tion. (a) Exponential(3) (b) Weibull(1.5, 0.5), meaning A = 1.5 and y = 0.5. (c) Log-logistic(1.5, 0.5)
