Contigency tables

Post by fibankuti »

Dear all,
I will be pleased if someone can help-me. I would like to use contigency tables appling comparative mesures qui-square (3x4 ). But in Jamovi there is only compartive 2x2.
Someone knows how to do it? is there some module for that?

Thank you!

You could try using Logistic regression, which will produce odds-ratios and other related results. For a 3x4, you would need to select N-outcomes (Multinomial), and put one variable (probably the 3-level) as the dependent and the other as a factor. Interpretation of the results will be tricky though and needs careful thought to understand what each figure represents.

Hi. jamovi's chi square contingency analyses aren't limited to 2 by 2. 3 by 4 works just fine.

That was my first thought, but the original query was specifically about the "comparative measures" output (odds ratios, etc.) that are only available for 2x2 tables. I couldn't see any other way to do this in jamovi.

Oh. Sorry. However, I think those comparative measures are only computable in situation where the analysis can be conceptualized as comparing two things (to proportions, two ratios, etc.). Thus, they only work for 2 by 2 tables:

I've seen computational procedures that automatically break a greater-than-two-by-two table into two-by-twos for purposes of calculating comparatives, but one could also just perform multiple analyses: the original n by n, along with the two-by-twos.
