In pwr2ppl: Power Analyses for Common Designs (Power to the People)

pwr2ppl 0.1.1.9000

This is a developmental release.

pwr2ppl 0.1.1

Submitted to CRAN. Accepted 6/12/19.

pwr2ppl 0.1.2

Updated 8/7/20

Corrected tfromd, anc, and lmm1w1b issues. Added text to clarify within subjects and mixed design sample sizes.

Functions for mediation are expanded and improved. Expanded med to accept 2 predictors and 4 mediators - note: this function is no longer the recommended approach to mediation power. Use med_js instead. med_js uses the joint significance test rather than a Sobel-like estimator. med_serial adds serial mediation.

There is a new folder called “betafunctions” where I will post developmental versions of functions I’m working on. My current target for development are some of the more common conditional process analyses.

pwr2ppl 0.1.0

Removed

pwr2ppl 0.2.0

Submitted 3/23/2021

Functions for moderated mediation (conditional process) models 7, 8, 14, and 15. medmod7, medmod8, medmod14, medmod15.

cleaned up a few errors in various functions.

pwr2ppl 0.3.0 Submitted 2/13/2022

Fixed a minor error in MRC_all. Added a beta function called Assumptions to address power under conditions of violated assumptions.

pwr2ppl 0.4.0 Submitted 4/22/22 Fixed error in assumptions

pwr2ppl 0.5.0 Submitted 9/5/2022 Removed modmed8 and modmed15 - need to clarify calculation of indirect effects. Corrected modmed7 and modmed14.

pwr2ppl 0.6.0 Submitted 12/22/2025 Rewrote within subjects ANOVA stuff because the people who maintained ez ghosted CRAN. Removed anc command – that isn’t working right and no one uses it.
