See also: nnrnet nnrpredict

Quantlet: ann
Description: a tool to run a feed-forward neural network

Usage: ann(x, y, t {, varname})
Input:
x n x p matrix, input variables
y n x q matrix, output variables
t n x 1 vector of sets (0=training, 1=test, 2=validation)
varname p x 1 vector, variable names (unused)

Example:
library("nn")
x = read("kredit")
t = read("tkredit")
y = x[,1]
x = x[,2:21]
x =(x-min(x))./(max(x)-min(x))
ann(x, y, t)
