Dear useRs,

I am analysing the behaviour of MLE for the two parameters of a kind of exponential distribution, leaving as initial values the estimators moments produced by the variation coefficient.

 I do using simulations, giving them an accountant, r. But running my codes remains a problem with the nlm function. To review details wearing

On one of the lines put status

cond04<-is.finite(mle.nlm$minimum)

        {
         .....

The error message is delivered:

Error en nlm(logdgenexpn, p = c(vmomest[[1]], vmomest[[2]]), x = x.genexp, :

        valor no finito provisto por 'nlm' Además: Hubo 50 o más avisos (use warnings() para ver los primeros 50)

One possibility is to re-generate the data set that produces such error, but not know how to do it.

Someone knows how to keep in an object the parameters of the generator which produces such shows.

l can send codes for details.

Thank you for your attention.
