lme question

["Frank Lawrence" <Cougar@psu.edu>]

Occasionally when I use glme in the correlatedData library, I receive some warning messages similar to this one: optim returned message NEW_X
 in: "LMEoptimize<-"(`*tmp*`, value = list(maxIter = 150, msMaxIter = 10, 

 

Is this message useful for diagnosing problems or is just informing me that one set of iterations did not converge?

 

Respectfully,
