Simulation-based power analysis for adaptive control designs

This package includes functions for conducting statistical power analysis for conflict designs (e.g., Stroop, Flanker, LWPC, ISPC, CSPC, etc.). The approach uses Monte-Carlo simulation. Parameters for variability in base reaction time distributions are used to sample single-trial data from an ex-Gaussian distribution, using the rexgauss function from the retimes package. The rexgauss function samples n observations from an ex-Gaussian distribution, with parameters mu (mean of a normal distribution), sigma (standard deviation of a normal distribution), and tau (exponent of an exponential distribution). See the article for examples.
