Limma instead uses a posterior variance that represents a weighted combination of sample variance and a more stable grand variance estimate that is approximated from all data on the array.

Making inferences about population differences based on samples of data, that is, performing intuitive analysis of variance (IANOVA), is common in everyday life. However, the intuitive reasoning of ...
