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

Link:
Usage: ann (x, y, t {, vn})
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)
vn p x 1 vector of variable names (unused)

Example:

x = read("kredit1")

t = read("tkredit")

y = x[,1]

x = x[,2:21]

x = (x-min(x))./(max(x)-min(x))

ANN (x, y, t)

Result:

runs a user specified neural network for the kredit data of 

Fahrmeier and Hammerle.
