Description Details Author(s) References Examples
This package implements a nonlinear Frumento and Bottai's (2015) method for quantile regression coefficient modeling (qrcm), in which quantile regression coefficients are described by (flexible) parametric functions of the order of the quantile.

The function niqr
permits specifying nonlinear basis for each variables. The function test.fit.niqr
permits to do goodness of fit.
The auxiliary functions summary.niqr
, predict.niqr
, and plot.niqr
can be used to extract information from the fitted model.
