Re: Multilevel modelling: center leve 2 predictors
That would be a very strange default setting. By default all continuous variables are grand mean centered. You can choose "centered clusterwise" in the "covariates scaling" panel if you want to center level 1 predictors at group means.

Re: Gamma Mixed Model, Posthoc Odds Ratio
Hi GAMLj3 implements posthoc tests for beta models (following R emmeans package) testing differences in probabilities (o proportions). So, the posthoc values are basically marginal effects for categorical independent factors. As such, the exp(b) would not make much sense. However, you can always get...

Re: Linear Regression Calculation differences
General Linear Model by default centers the covariates to their mean, whereas Linear Regression does not. So, when your variables are entered as covariates and there is an interaction in the model, the first order effects are different. If you center your variables or in GLM set the scale to "n...

Could you tell us the jamovi version and the version of GAMLj you work with?

Re: How to test for support for random slopes using both frequentist methods and Bayesian methods
In gamlj you have the LR test for random slopes variances. We do not have bayesian lmm yet, but I do not expect results to be very different between maximum likelihood (what people would call frequentist) and average likelihood (what people call bayesian)
