Dear nlme-authors,
Hello my name is Heejin Jin, a master student of Seoul National
University in Korea.
I have a question about lme function in nlme package.
First, I got an error message from R such as it can't be converge.
So, I used option "singular.ok=TURE" which makes the model to converge.
I wonder that can I trust the results from this option ?
Second, there are options to control iteration numbers.
If I used too many iteration numbers, then the velocity getting slow
than default?
I look forward to hearing from you soon.
Thanks !
Sincerely
Heejin Jin
