Error in mvOU #2

Closed rafmarcondes closed 7 years ago

rafmarcondes commented 7 years ago

I'm getting the following error when I try running mvOU:

mvOUM_f=mvOU(tree=map_tr, data=mvmorph_input, model='OUM', echo=F) Error in optim(par = c(alpha, sigma), fn = function(par) { : L-BFGS-B needs finite values of 'fn'

mvBM seems to run normally.

mvMORPH 1.0.9 R 3.3.3 Mac OS 10.12.5

map_tr.R.zip mvmorph_input.R.zip

Please suggest a workaround, if there is any.

Dear Rafael,

I'm sorry I can't open the files you embodied in the gitHub issue page. So I can't reproduce your error.

This kind of message probably mean that there were a problem when computing the log-likelihood. It's possibly a singularity issue. Try using safer algorithms such as method="inverse", or method="pseudoinverse" (although slower...). There are some more informations about the various algorithms on the package vignette.

Please send codes and related dataset by mail, it will be easier to track.

All the best,

Julien
