qrnn: R package for the quantile regression neural network model

Description

This package implements the quantile regression neural network (QRNN) (Taylor, 2000), which is the artificial neural network analog of linear quantile regression. The QRNN formulation follows from previous work on the estimation of censored regression quantiles, thus allowing predictions for mixed discrete-continuous variables like precipitation (Friederichs and Hense, 2007). A differentiable approximation to the quantile regression cost function is adopted so that a simplified form of the finite smoothing algorithm (Chen, 2007) can be used to estimate model parameters. Quantile-based distribution functions are provided following Quinonero-Candela (2006).
