%description
Tools for linear, nonlinear and nonparametric regression and
classification.  Novel graphical methods for assessment of parametric
models using nonparametric methods. One vs. All and All vs. All multiclass
classification, optional class probabilities adjustment.  Nonparametric
regression (k-NN) for general dimension, local-linear option.  Nonlinear
regression with Eickert-White method for dealing with heteroscedasticity.
Utilities for converting time series to rectangular form.  Utilities for
conversion between factors and indicator variables.  Some code related to
"Statistical Regression and Classification: from Linear Models to Machine
Learning", N. Matloff, 2017, CRC, ISBN 9781498710916.
