Changes in version 1.1.1 (2025-08-19) - Enhance print method with type of measure being used for choosing $M$ and $\nu$ - Allow for cases where $p < n$. - Allow specification of possible beta values in simulate_spareg_data(). - Changed robust example in vignette to using a poisson() link. - Reproducibility of parallel case is introduced using doRNG. - Added extractor function extract_spareg() to extract fitted values, residuals, and coefficients from a fitted model. - Added extractor function get_model() to extract the best or the 1se model. - Added extractor function get_measure() to extract the table of (cross-) validation measures for the grid of (nu, nummods). - Added class coefspar with print and summary methods to improve the usability of the coef method. - Added extractor functions get_intercept() and get_coef() to extract the intercept and coefficients (non-standardized) from the coefspar objects. - Added avg_type i.e., type of averaging the marginal models to spar(). This argument is used in computing the validation measure. - Removed coef argument from predict method. - Added aggregate = c("mean", "median") argument for predict method. Changes in version 1.1.0 (2025-07-18) - Improved man pages. Changes in version 1.0.0 (2025-05-06) - Initial CRAN submission.
