Introducing PowerLMM.js!
A new tool for power analysis of longitudinal linear mixed-effects models (LMMs) – with support for missing data, plus non-inferiority and equivalence tests.

Would really appreciate your feedback as I refine this app! Details below 🧵👇

One request: can you make the Cohen's D go to two decimal places (i.e., d=0.15)?
We have developed a shiny app with a similar purpose for log lineair growth models- we should maybe chat at some point? https://utrecht-university.shinyapps.io/Power_growth_models/
• Conduct power analyses for LMMs comparing rate of change across groups.
• Account for random slopes and missing data.
• Supports non-inferiority and equivalence tests.
• Provides tools to visualize core features of the model

(No honestly this is really amazing. What is "Last time point"? Maybe the input fields can have little question marks that show info on hover.)
(On a serious note, I’m planning to offload these matrix computations from the main thread in the next release.)
seq(0, last_time_point, length.out = n1)
I think "duration" could be a better term? Will add question marks!
