Correction to: Statistics in Biosciences https://doi.org/10.1007/s12561-019-09259-x The original version of this article unfortunately contained an error in ‘R code’ under Appendix section. In Models 3 and 4, the numeric variable “treat” should be in the fcluster random effect instead of the factor variable “ftreat.” Therefore, the correct R code should read as follows: # Model 3 lmer(y ~ ftime + ftreat + (1 | fcluster) + (0 + treat | fcluster) + (1 | clustime)) # Model 4 lmer(y ~ ftime + ftreat + (treat | fcluster) + (1 | clustime))
