Simr power analysis error

WebbThe powercurve function from the simr package in R (Green & MacLeod, 2016) can incur very long running times when the method used for the calculation of p values is Kenward-Roger or Satterthwaite (see Luke, 2024). Here I suggest three ways for cutting down this time. Where possible, use a high-performance (or high-end) computing cluster. This … Webb16 feb. 2024 · SIMR power analysis revealed that 42 participants were needed to reach >80% statistical power to detect differences between the memory and perception conditions. Footnote 1 Thus, given our sample size of 77 participants, we concluded that we had sufficient power to study the effect of interest.

A sensitivity power analysis fixes the sample size, desired power, and alpha level, and answers the question which effect size a study could detect with a desired power. A sensitivity power analysis is therefore performed when the sample size is already known.

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.
