WebTitle Calculate Power and Sample Size with Beta Regression Version 1.1-1 Date 2024-09-13 Description Power calculations are a critical component of any research study to determine the minimum sample size necessary to detect differences between multiple groups. Researchers often work with data taking the form of proportions that can be modeled with Web3 Feb 2024 · PROC POWER can answer that question, too. It turns out that a sample size of N=1000 only results in 0.25 power and a sample size of N=2000 only results in a power of 0.39. A pilot study based on those smaller samples is a waste of time and money because the study isn't large enough to detect the small effect that the company claims.
