convergence warning in betamix()
Hi, I am running some rather complex mixtures of beta regressions using the
betamix() command from the betareg package (V. 3.0-4). If I am doing
exploratory regressions with only one random starting value (nstart=1) I
obtain results which converge after about 100 iterations. However, if I run
regressions with nstart=100 random starting values I obtain solutions

Fitting 3 beta distributions

I want to fit 3 beta distributions to my data which ranges between 0 and 1.
What are the functions that I can easily call and specify that 3 beta
distributions should be fitted?
I have already looked at normalmixEM and fitdistr but they dont seem to be
applicable (normalmixEM is only for fitting normal dist and fitdistr will
only fit 1 distribution, not 3). Is that right?
Also, my data has 26
