[Beta Testing] ChiSquaredTools - Post-Hoc Analysis Module

[GmA]

Hi all,
I'm looking for testers for ChiSquaredTools, a Jamovi module for chi-squared analysis which I have recently out together.
Current tool: Post-Hoc Analysis featuring six metrics (standardised residuals, adjusted residuals, Quetelet Index, IJ Factor, PEM, median polish) to identify which cells drive significant associations.

Key features:
Colour-coded significance (red/blue)
Auto-generated summary tables
Built-in interpretation guidelines & references
Optional Šidák correction
More tools planned for future releases

Interested? Reply here or email gianmarco.alberti@um.edu.mt for the .jmo file.

Thanks!
Gianmarco

Hello,
The latest jamovi also has some post-hoc tests. I have also tried to make a post-hoc test for Chi-Sq, to be used in clinical research. It basically makes multiple 2x2 analysis with p value correction. It is here: https://github.com/sbalci/ClinicoPathDe ... sttest.b.R
I would like to see your approach as well. Please share the code or jmo file.

Hello,thanks for pointing out your module.

As for Jamovi post-hoc tests, yes I know them. However, for educational purposes (social science) I wanted to add some other measures which I have been seen scattered here and there in literature, and that made sense to me.

Here it is the .jmo file, but please note that I have still facing an issue with the formatting of the decimal digits in some of the produced tables, and I have just posted a question in this same section of the forum.

I managed to fix the decimal digits issue.
The fixed version is attached here.

Ciao Gianmarco,
I greatly appreciate your decision to bring your chisquare package over as a dedicated jamovi module.

I believe this module will garner significant interest once it is available in the library.
I haven't been able to locate the module in your public repository; I would be keen to take a look at it from a developer's perspective.

And your book, has it been written and put on sale? I hope the public enjoyed it.

Cordiali saluti,
Maurizio

Ciao Maurizio,
thanks for your follow up, and for you kind comments.

Let me provide you with some more context.
I have been involved in categorical data analysis for both my research and teaching. For the first, I have been always using R, and I have developed my own stats tool. As a matter of fact, I am the author and maintainer of a number of R packages, among which the 'chisquare' package which sits on CRAN.

I had always in mind to "transfer" some of the features of 'chisquare' to a Jamovi module, and I never managed because I must admit that the programming of a Jamovi module is a bit beyond me. I am glad to have accomplished some positive steps with the help of AI: it was not easy, but by trial and errors I managed to put together the module mentioned in this thread. This links to the second field I was mentioning: teaching.

I am using Jamovi for teaching stats at undergraduate and postgraduate level at the University where I work, and I am very happy with this. However, I realised that some of the "things" I wanted my students to use in categorical data analysis were either not available or dispersed across different modules. This was the additional reason that pushed me to create my "own" module.

You are completely right: I should put the module on my GitHub, which to be honest I am not using since long time. I must confess that teaching, research, and administration are taking 95% of my time, and my programming schedule develops pretty hectically.

As for my book (thanks for mentioning it, actually I am amazed you remembered), yes it has been published in July 2024, so a bit more than 1 year ago:
https://www.routledge.com/From-Data-to- ... 1032720388

I am pretty happy with it: the sale figures are not bad (for such type of book), and it got 4 academic citations in about one year.

Should you want to give the module a go, I would be glad, even if simply using the .jmo file I have shared here.

Since, as usual, I try to make my tools "usable" by both experts in the fields and novice practitioners, today I tried to add some optional annotations that provide some more theory (in an pretty accessible fashion, so that the average student can relate). This latest version (still under development) is attached here. I must confess I am still having hard time to get something to work, and I will post a question soon in this forum.

Hope the above helps to provide some more background info about the module and my "programming" philosophy.

Cari saluti
Gianmarco
