We’ll keep updating it and more features to come in the near future. Feedbacks welcome. Happy planning! 💪🏼

Particularly for contextual meta-collinearity, which is less intuitive as a meta parameter, you may follow the step-by-step interactive process to get a recommended value.

Additionally, we provide detailed guidelines on setting the focal effect γ and the contextual meta-collinearity ρ_c.

Based on your inputs, it automatically generates a write-up template that you can conveniently adapt to justify nmax as the planned sample size for your proposed study.

You can also see how nmax value changes with the standardized focal effect γ.

In the published paper we detailed the steps to get the target sample size using our nmax equation.

Now with the Shiny app, you can easily obtain the target nmax value by simply sliding the inputs. No code or math equation needed! Everything you need, in one place.

A few weeks ago you’ve heard about nmax as the insurance policy for sample size planning on @quantitude.bsky.social

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!

Thanks Tom! 😆 We had a lot fun doing the project (after being “fired” for too many times due to budget cuts…)

Seeing our shadow tomorrow…

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! 👉🏼

Thanks Willa! I was missing Jiffy too!

Oh sorry I must misread it didn’t I lol. My brain was toasted being getting stuck in the airport after a terrible delay since midnight! 😴

lol Thanks Laura! The dressing code in the dissertation guidelines does sound very serious. 😉

Thanks, Wes! 😊
