How does the skill handle correlated predictors?

It provides a QR decomposition implementation for Stan which decorrelates the predictors during sampling, significantly improving Markov Chain Monte Carlo (MCMC) efficiency.

Does this skill support both Stan and JAGS?

Yes, it provides side-by-side implementation patterns for both Stan and JAGS across linear, logistic, and Poisson regression models.

What is the benefit of robust regression in this skill?

The robust regression pattern uses a Student-t distribution instead of a normal distribution, which allows the model to be less sensitive to outliers in the data.

Does it provide guidance on choosing priors?

Yes, it includes a reference table for weakly informative priors for intercepts, coefficients, and scale parameters based on recommendations from experts like Andrew Gelman.

Is this skill suitable for count data?

Absolutely. It includes both Poisson regression for standard counts and Negative Binomial regression for scenarios where the variance exceeds the mean (overdispersion).
