Hiemstra Hi Anthony, When the individual calls passed on to the cluster are very short (which might be the case for your bootstrap), the overhead of running them parallel becomes very large, negating the positive effect of running the processes parallel. The lme4 is an excellent package, written by the mixed-models Guru Douglas Bates. I will not talk here about choosing wether a grouping variable (sites, individuals …) should be included as a fixed term or as a random term, please see Gelman and Hill (2006) and Zuur et al (2009) for […]. In the present meta-analysis, we compiled data from 75 longitudinal studi. However, another possible solution is generalized ordinal regression.
