Subject: predict.lme() gives missings for new subjects
Hi,
why does predict.lme() give missings in the "predict.Subject" column for Subjects which are not in the original training set?
library(nlme)
example(predict.lme)
## c.f. Subject=="F30" has missing values.
How can I predict/impute values for such "new" Subjects based on the fitted model?
Thanks in advance,
Will
