Oops, I've made a mistake in my former post. the corrected message is: Hi there,
I would like to know the distribution of a linear combination of (not identical) logistically distributed variables, i.e. f(x) = exp( (x - alpha)/beta )/(1+exp( (x-alpha)/beta ))^2 . Does anybody now what this distribution would look like, or know a good reference? I've looked in the 'Handbook of the logistic distribution' by Balakrishnan, as well as in Johnson & Kotz, but couldn't find anything. Since the distribution is very similar to the normal, I would expect a similar result to that for the normal distributed (it is logistically distributed itself). Thanks for your help.
