Synthetic Power Analyses: Empirical Evaluation and Application to Cognitive Neuroimaging. (arXiv:2210.05835v1 [cs.CV])

In the experimental sciences, statistical power analyses are often used
before data collection to determine the required sample size. However,
traditional power analyses can be costly when data are difficult or expensive
to collect. We propose synthetic power analyses; a framework for estimating
statistical power at various sample sizes, and empirically explore the
performance of synthetic power analysis for sample size selection in cognitive
neuroscience experiments. To this end, brain imaging data is synthesized using
an implicit generative model conditioned …
