The package also identifies\nwhich individual mediators are active with familywise error\nrate or false discovery rate control. The methods implement Yu\nand Kelley (in press), \"Power Enhancement in High-Dimensional\nHeterogeneous Mediation Analysis\" (Journal of the American\nStatistical Association); the package also simulates mediation\ndata under the homogeneous, heterogeneous, and contrasting\npatterns that the article studies, ships its empirical\nhealth-expenditure data as a benchmark and reruns that\nempirical analysis, and runs the designs of its Monte Carlo\nsize and power studies. The name, 'POEMED', from POwer-Enhanced\nMEDiation, encodes the method. Every estimation and testing\nfunction returns a tidy 'data.frame' that prints with sensible\nrounding and composes with the broader R ecosystem.", "License": "GPL (>= 3)", "Copyright": "Xiufan Yu and
