POWERMAP: Stata module to create power heat maps for experimental design using multiple periods
Cristhian Pulido · RePEc: Research Papers in Economics · 2020
powermap creates power/sample heat maps for experimental designs with multiple periods. powermap conducts analytical power/sample calculations and plots a heat map for all the combinations of pre-post treatment periods, hence illustrating the trade-offs of multiple measurements for experimental design. The program allows two approaches: (i) a heat map of the statistical power of all the pre-post rounds combinations for a given study sample size n(#); (ii) a heat map of the total study sample size required by each pre-post rounds combination to achieve a power of power(#).
