Description: An extensible expectation-maximization (EM) framework for
        finite mixtures of quantile regressions (clusterwise /
        mixture-of-experts quantile regression). A single EM substrate
        with an engine/extension contract carries a family of
        capabilities: the core free-weight mixture of Wu and Yao (2016)
        <doi:10.1016/j.csda.2014.04.014> -- a fast asymmetric-Laplace
        path and the nonparametric kernel-density EM with components
        constrained to have their tau-quantile equal to zero (Hall and
        Presnell 1999 device); expectile and M-quantile component-loss
        families (Newey and Powell 1987; Breckling and Chambers 1988);
        component-specific penalized variable selection (SCAD /
        adaptive-LASSO, the quantile analogue of Khalili and Chen
        2007); and joint multi-quantile estimation with a shared latent
        classification and non-crossing component curves. Provides
        classification-aware standard errors (sparsity and
        stochastic-EM multiple imputation), multi-start estimation,
        component-count selection, and prediction. The companion
        package 'mixqrgate' adds location-varying gating.
