ploterrcorr
Plot autocorrelation of error time series
Syntax
ploterrcorr(error)
ploterrcorr(errors,'outputIndex',outIdx)
Description
ploterrcorr(error) takes an error time series and plots the
autocorrelation of errors across varying lags.
ploterrcorr(errors,'outputIndex',outIdx) uses the optional property
name/value pair to define which output error autocorrelation is plotted. The default is
1.
Examples
Plot Autocorrelation of Errors
Here a NARX network is used to solve a time series problem.
[X,T] = simplenarx_dataset;
net = narxnet(1:2,20);
[Xs,Xi,Ai,Ts] = preparets(net,X,{},T);
net = train(net,Xs,Ts,Xi,Ai);
Y = net(Xs,Xi,Ai);
E = gsubtract(Ts,Y);
ploterrcorr(E)
