Weibull Models

a SAS macro for the adaptive testing, and in the Appendix he gives other macro for estimation and confidence interval building. To convince the reader to use these adaptive methods, the author gives an argument that relies mainly on some small simulations. From the simulations, the adaptive procedures perform better than the usual nonadaptive least squares methods in many situations. The major problems I had, which may also deter a statistician from using these procedures are as follows:
