gbkreg2d - Kernel non linear regression for bivariate data


gbkreg2d [options]


2D kernel estimation of conditional moments. Data are read from standard input as triplet (x,y,z). The moments of z are computed on a regular grid in x and y The kernel bandwidth if not provided with the option -H is set automatically. Different bandwidths can be specified for x and y. Different moments are given in different data block. Options -n, -f, -H and -S accept comma separated values to specify different values for x and y components


number of points where the estimation is computed (default 10)
fraction of the support for which to print the result (default .9)
set the kernel bandwidth explicitly
scale the kernel bandwidth with respect to heuristic 'optimal'
choose the kernel: 0 Epanenchnikov, 1 Rectangular, 2 Silverman type I 3 Silverman type II (default 0)
set the output, comma separated list of m mean, v standard deviation, s skewness and k kurtosis (default m)
switch off data de-variation procedure
verbose mode
specify the input fields separators (default " \t")
