Re: [R] how to express time series linear model Q(t) ~ Q(t-1)+.. Q(t-n) as a formula

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 CJ Rubio wrote: For example I have a time series Q(t) ~ Q(t-1) + Q(t-2) + Q(t-3) meaning

[R] how to express time series linear model Q(t) ~ Q(t-1)+.. Q(t-n) as a formula

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) -- View this message in
