Simr power analysis error
WebbLearning the simr package is much easier than learning to construct your own function to conduct power analysis for mixed models; There are many parameters to estimate and Brysbaert & Stevens (2024) suggest working from pilot data to estimate these parameters before moving forward. Otherwise we have know way to guess what is going on. Webb12 jan. 2024 · Because of the missing values (errors, outliers): the means of the F1 and the F2 analysis are not the same. There is no straightforward and well-established way to combine F1 and F2 into a single measure indicating the significance of the effect.
