Other arguments, not used. |
Extract the fitted coefficients for a linear or logistic regression model, or a grouped list of such models.
For ungrouped regressions, a named numeric vector giving the fitted coefficients.
For grouped regressions, a list giving the coefficients for each of the component models.
