TSA ARMA Prediction (Waveform)

number of points specifies the length of the predicted time series. The default is 1.
Xt specifies the univariate time series.
AR coefficients specifies the AR coefficients of the autoregressive-moving average model. You can obtain the AR coefficients using the TSA ARMA Modeling VI.
MA coefficients specifies the MA coefficients of the autoregressive-moving average model. You can obtain the MA coefficients using the TSA ARMA Modeling VI.
error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
noise variance specifies the variance of the white noise series of the autoregressive-moving average model.
predicted series returns the predicted univariate time series.
standard deviation returns the standard deviation of each predicted value.
error out contains error information. This output provides standard error out functionality.
