Dear Community,

I am trying to plot the cohort group effect by country after estimating Hierarchical Age Period Cohort Model (HAPC):

This is the model - binary outcome variable with four levels (country, cohort group, period and individuals), cross-classified:

Dear George,

Thank you very much for the guidelines. It is very helpful.

Dear Community,

I am trying to replace margins command after the three-level multilevel model with a lower-level interaction effect fitted in runmlwin (Stata/SE 15.1).
The single-level regression analysis is written as follows with margins command at the end:

Dear Community,

I have difficulties to interpret the results of the between-country variance function.

In the random slope model, I hypothesize that the effect of internal efficacy varies across countries in a relationship with the propensity to vote among young voters. Covariance structure of ...

Dear Bill,

Your suggestion to put L2 variables first in the model worked very well.
Thank you very much for the suggestion and help.

Dear Community,

I have specified the orthogonal option in discrete models based on Browne's (2012) recommendation.

In order to increase Effective Sample Sizes of the contextual variable in the contextual-effects model, I have added hierarchical centering in MCMC as follows:

* Run the model ...

Dear Users,

I am using runmlwin within Stata(15.1) in macOS (High Sierra).
Referring to Lemma 7.5, I am trying to plot the country prediction lines for the random slope (in my case Internal Efficacy). However, I cannot see explicit 'fanning in' given the covariance is negative. Any help would be ...

Dear Chris,
