Description: Implements S-type ridge regression, a robust and
 multicollinearity-aware linear regression estimator that combines S-type
 robust weighting (via the 'Stype.est' package) with ridge penalization;
 automatically selects the ridge parameter using the 'ridgregextra'
 approach targeting a close to 1 variance inflation factor (VIF), and returns
 comprehensive outputs (coefficients, fitted values, residuals, mean
 squared error (MSE), etc.) with an easy x/y interface and optional
 user-supplied weights. See Sazak and Mutlu (2021)
