Quality measures - pseudo-R-squared, Percent certainty, AIC, BIC

Dear Sawtooth Community,

I have some questions concerning the measures of model quality SSI displays:

1) When performing a logit estimation, the results table shows a measure "Percent Certainty". Is this the same as "peudo-R-squared" (as I read somewhere in the Help-function)?

2) Which of the several pseudo-R²s is calculated by SSI?

3) What is the description/interpretation of the other measures provided, such as AIC, BIC, ...?

4) When performing an HB analysis, where are the measures of model quality (only the differences are shown, when using the CBC Interaction Search Tool)?

Thank you in advance for your support!
Michael
