When using mix() form the mixdist package, I sometimes get NA's and NaN's in the Standard Errors estimates. I've understood from the code that mix() it is using Non-linear minimization (nlm) to estimate thoses errors, but I can't understand how to interpret theses results. Does any one have a (web) reference to suggest or an interpretation ?
