Hi, the package bs, version 1.0, is available. Yet, I've gote some problems with it, specifically with the maximum likelihood estimation of the parameters \alpha and \beta of Birnbaum-Saunders distribution. Let the following code run: library(bs) alpha<-1.5 beta<-0.5 n<-100 set.seed(1) x<-rbs(n,alpha,beta) est1bs(x) The MLE algorithm does not converge. Not only for this pair of values and for this sample... Please have a look...
