Dear all, Iam looking for some R code with makes me able to analyze data with equal discrimination parameters (just like the Rash model) by the bootstrap method with 1000 bootstrap samples. Also can someone tell me how to get the bias and estimated standard error of this discrimination parameter with the bootstrap method in R? Iam trying to analyze results of the Rash model versus the bootstrap method.
