NEURAL NETWORK MODELS

Overview

A graduate level introduction to and illustrated tutorial on neural network analysis.

Why we think it is important: Neural network analysis is a valuable tool for prediction of continuous target variables or classification of categorical target variables. It is robust for noisy and missing data, and is particularly useful when nonlinear relationships which cannot be addressed through data transformations or generalized link functions exist in the data.
