lmer() causes segfault
...se slopes with individual-level and group-level characteristics. Thus, I have hierarchic data with three levels (measurement time, individual, group). With lme() (from the nlme package), this is my first simple model: mod1 <- lme(fixed = performance ~ time, random = ~ 1 + time | GroupID/StudentNumber, data = dataset.long, na.action = na.omit) It fits to the data well. I tried to specify the same model in lmer(): detach("package:nlme") library(lme4) mod1 <- lmer(performance ~ time + (time | GroupID/StudentNumber), data = dataset.long, na.action = na.omit) However, this...
