Description: Implements the dynamically weighted modified maximum likelihood
 ridge (DWMMLR) regression estimator, a robust and multicollinearity-aware
 linear regression estimator that combines the DWMML3 weighting procedure of
 Sazak (2019) <doi:10.1080/00949655.2019.1571060> with ridge penalization to
 address both outlier sensitivity and variance inflation due to
 multicollinearity. The ridge parameter is selected automatically using the
 approach implemented in the 'ridgregextra' package (Karadag, Sazak, and
 Aydin, 2023) <https://CRAN.R-project.org/package=ridgregextra>, described
 further in Karadag, Sazak, and Aydin (2026)
 <doi:10.1080/02664763.2026.2655681>, which targets a variance inflation
 factor (VIF) close to but not below 1, removing the need for manual tuning.
 Returns comprehensive outputs (coefficients, fitted values, residuals, mean
 squared error (MSE), standard errors, R-squared, and adjusted R-squared)
 through a simple x/y interface.
