Description

In cases where some tests like het_breushpagan rejects the Null of no heteroscedasticity it would be interesting to look at which auxiliary variables are significant in the artificial direction.

This would help in getting an idea in which "alternative direction" the Null is rejected.
In this case, what would be likely candidates for including in estimating a variance function.

(not only for linear_model, I looked at a case with heteroscedasticity after estimating a Poisson model)

Research direction

Start by reviewing the het_breushpagan diagnostic and the result objects used by linear_model and Poisson models. Define which intermediate auxiliary-variable results should be exposed and how callers would identify significant variables or alternative directions; no specific files or tests are named in the issue.
