How to run repeated measure correlation in JMP (Non-independent data)

Thierry_S — Fri, 09 Jun 2023 00:52:48 GMT

Hi JMP Community,

I want to determine the correlation between repeated measurements (time 1, time 2...) of biomarkers and a clinical measure evaluated at the same time points in multiple patients. I am aware of the pitfall of using the standard correlation method with the time points combined because of the lack of independence of the data.

I found an article online describing an R script to conduct this procedure (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5383908/#:~:text=Repeated%20measures%20correlation%20(rmcorr)%20is,more%20occasions%20for%20multiple%20individuals.).

Is it possible to perform the same analysis (i.e., repeated measure correlation) in JMP?

Thank you.

Best.

I forgot to mention that I work with JMP 16.1 (no JMP Pro) on Windows 10 Pro operating system.

Hi @Thierry_S ,

I'm not expert here, thats why I consumed some presentations recently,

with JMP Pro I would recommend:

Fitting Repeated Measures Data using JMP Pro - JMP User Community

and other contributions in Mastering JMP.

But in this contribution I found recently several hints on how to do similar things w/o JMP Pro in the Fit Model Platform:

Building Linear Mixed Models using JMP® Pro 15 - JMP User Community

Hope that helps a little.

@Georg thanks for the tips.

Best,

Quantitative method aside, I believe you can create the plots and do graphical analysis and apply practical evaluations of the repeated measures with JMP. Graph builder would be useful. Also don't forget to test for unusual data points and range charts might help there.
