ANN is an Artificial Neural Network program that learns relationships between variables, and is able to predict the value of a dependent variable based on the values of independent variables. ANN supports two types of neural networks. The first network, ANN1HL, has 1 hidden layer. The second network, ANN2HL, has 2 hidden layers. The number of nodes in each hidden layer, and other parameters, are set by the user. ANN includes online help, a sample data file and a publication describing the use of neural networks.
