Analysis of variance (ANOVA) is an extremely important method in exploratory and confirmatory data analysis. Unfortunately, in complex problems (e.g., split-plot designs), it is not always easy to set up an appropriate ANOVA. We propose a hierarchical analysis that automatically gives the correct ANOVA comparisons even in complex scenarios. The inferences for all means and variances are performed under a model with a separate batch of effects for each row of the ANOVA table. We connect to… Expand

Fixed or random? On the reliability of mixed-effects models for a small number of levels in grouping variables

- Biology
- 2021

It is found that mixed-effects models already correctly estimate the variance of a random effect with only two groups and inferring the correct random effect structure is of high importance to get correct statistical properties, which allow for more informative choices about study design and data analysis and thus make ecological inference with mixed- effects models more robust for small number of groups.
