...ls use three fixed effects: x1 is a two level factor; x2 and x3 are continuous. We are including random intercepts for YEAR and SITE. On subject-matter considerations, we are also including a random coefficient for x3 within YEAR. Neglecting the log link, the model is y_{i,j} = x'_i \beta + \eta_i + z'_i \phi_j + \epsilon_{i,j} where i indexes SITE and j indexes YEAR, \beta is the vector of fixed effects \eta_i in the random intercept for SITE and \phi_j are the random intercept and coefficient for YEAR. I have written x'_i because the covariates are assumed (reasonably) t...

Hi, I have been looking for an R package which allowed to do meta-analysis (both pairwise and network/mixed-treatment) at arm-level rather than at trial-level, the latter being the common way in which meta-analysis is done. By arm-level meta-analysis I mean one that accounts for data provided at the level of the individual arms of each trial and that does not simply derive the difference between
