Re: Random Regression Model

Dears,
 
does anyone of asreml users in legendre polynomial random regression models experianced situations in which hundreds to thousand iteration to convergence?
could it be natural?
I faced this problem in most of my analyses in rrm frame and don't know how to get rid of it.
 
thanks for any recomendation.

Thanks Arthur.

One other question - I've been asking a few people around here what the best way of determining what order polynomial to use in the fixed regression component of the random regression model?

It has been suggested that I consider either the F value for leg(age,1) but it doesn't appear in my output files or to compare the var(e) from different orders of fit. Is there any way of getting an F value?

Many thanks
Boyd
