I’m starting as a new Assistant Professor in Quantitative Psychology at @UCLA. Thrilled to be teaching a course on SEM this winter quarter. Really looking forward to a full quarter of excitement diving into SEM with the students!

A few months ago we introduced nmax as your insurance policy for sample size planning. @GregoryRHancock

Today we’re excited to launch the nmax Shiny app. Sample size planning with nmax can now be done in just a few button clicks!

So excited to share our new paper! 🥳 We introduce a new method and a new perspective for sample size planning, to ensure statistical power despite the great uncertainty. It greatly simplifies the planning process too! Check it out! 👉🏼
