Adding resources to page

Hi! I was about to start a Wikiversity page about statistical power related to some classes I am teaching, but decided to check first whether one existed. One does!

If no one objects, then in a week I will start adding some resources and material. My goal is to be a helpful collaborator, not a raider. I am happy to email or talk by Zoom if helpful, too. My Wiki editing is meant to be highly transparent, and I am open to using other formats to improve communication and work together effectively.

I use the G*Power software a lot for teaching and research, and augment with other things as projects or questions require.

These are resources and examples that extend into more intermediate and advanced/specialized options, too.

• The WebPower tool seems to have some useful options
  • E.g., there’s a power computation for 3-arm repeated measures trial here (not quite what we need, but maybe helpful)
  • This page shows the underlying R functions for WebPower – maybe we could reverse-engineer something
• Rizzo’s Statistical Computing in R has a chapter on power simulations
• This page has some info about using the R package pwr along with lme4 and simr

• Here is free power software and manual that is designed for hierarchical linear models (HLM), also known as mixed effects regression models: http://hlmsoft.net/od/
