Request: Pairwise contrast in estimated marginal means

Post by ricclo »

Thank you for a great software!

I would like to request that pairwise contrasts and their inference is incorporated into the modules. In the current form it is not possible to compare groups.

All the best

do you mean post-hoc tests?

Yes, please. I am trying to replace the need for SPSS with Jamovi and one of the functions that I tend to miss is the posthoc pairwise comparison in the estimated marginal means (i.e., corresponding to the emmeans in R).

It would be useful with a transformation ability to the estimated marginal means contrast in generalized linear models (i.e., for odds-ratios to risk ratios in logistic regression, similar to contrast(regrid(emmeans())) ).

All the best,
Rico

hi,

i think you'll find jamovi already provides post-hoc tests and estimated marginal means for linear models.

Hello,

Here comes a late addition to this request. Is it possible to incorporate posthoc marginal means to the binomial logistic regression models?

Currently, one can get the estimated marginal risk for a variable (e.g the probability of outcome=1 for man and woman separately), but as far as I can see, point estimate and 95%CI is not provided for their relationship, i.e the marginal risk ratio/marginal risk difference of the two.

In R: marginalmeans::avg_comparison can be used to compute such output.

Thank you for a great program.
