lme() with known level-one variances
Greetings,
I have a meta-analysis problem in which I have fixed effects
regression coefficients (and estimated standard errors) from identical
models fit to different data sets. I would like to use these results
to create pooled estimated regression coefficients and estimated
standard errors for these pooled coefficients. In particular, I would
like to estimate the model
\beta_{i} = \mu +

nlme gls() error
...varIdent(form=~1|strata)
I get the error
Error in recalc.corSymm(object[[i]], conLin) :
NA/NaN/Inf in foreign function call (arg 1)
My dependent variable is highly positively skewed and has with many zero
value.
Any ideas as to the cause of the error? Could I play around with any of
the glsControl values to help out?
Thanks
Richard
