...ng but the fitting in the tail (e.g. all observations > x or the n highest values). Standard ML-estimation sometimes doesn't work here very well. We see that especially when we have truncated datasets the algorithms won't converge. In the case of lognormal distribution: It seems that the farer the truncation point is away from the peak of the whole distribution the more unlikely is the convergence. So I think to do the following. And my questions are: Before I try to do it with basic R-knowledge on my own ... maybe there is a similar solution already available in R. And: maybe somebod...
