NAME
gbnlqreg - Non linear quantile regression
SYNOPSIS
gbnlqreg [options] <function definition>
DESCRIPTION
Non linear quantile regression. Read data in columns (X_1 .. X_N). The model is specified
by a function f(x1,x2...) using variables names x1,x2,..,xN for the first, second .. N-th
column of data. f(x1,x2,...) are assumed i.i.d.
