Re: [R] Network meta-analysis, varConstPower in nlme - Thank you!

Excellent - now it works. Thank you, Christian! (I still seem to be unable to replicate the results as reported in the paper, but that is unrelated to R-help. Thomas, do you have any idea what I may have entered wrongly?) Best, Christian Christian Ritz wrote: Hi Christian, I believe that the
