For example I have a time series Q(t) ~ Q(t-1) + Q(t-2) + Q(t-3) meaning that my current value is dependent to the 3 previous values. Can anybody help me express this in a formula that I can use for my neural network model (I am planning to use packages "nnet" and "MASS")

Hello, You may problably need to create the lagged vars yourself and use them as input for the NN. Best regards, Carlos J. Gil Bellosta http://www.datanalytics.com http://datanalytics.wordpress.com
