clustEff: Clusters of Effects Curves in Quantile Regression Models

Clustering of curves based on a dissimilarity that combines the concordance of their shapes and their closeness, as proposed by Sottile and Adelfio (2019) <doi:10.1007/s00180-018-0817-8>. The method can be applied to the effects curves of quantile regression coefficients models fitted with 'qrcm', with univariate or multivariate responses, and to curves observed in time, as in functional data analysis. The package also implements the clustering of waveforms by trimmed k-means of functional principal component scores (Adelfio, Chiodi, D'Alessandro and Luzio, 2011).
