Estimated Time Series Model
Object containing a time series model, data, and estimation information.

in the first usage an object from which a TSestModel object can be extracted (or constructed).
The TSestModel class of objects are generated by estimation methods. See, for
estVARXls. They contains a time series model (TSmodel),
data (TSdata), and information obtained by evaluating the model
with the data in an element called
The negative log likelihood function value (a vector of the total, constant, the det part, and the cov part)
The estimated residual covariance.
The one step ahead predictions (see predictT below). These are aligned with output data so that residuals are pred[1:sampleT,] - output[1:sampleT,]
The end of the period (starting from 1) for which output is used for calculating one step ahead predictions.
The end of the period for which the model is simulated. sampleT must be less than or equal predictT. If predictT is greater than sampleT then each step ahead beyond sampleT is based on the prediction of the previous step and not corrected by the prediction error.
estimates may optionally also contain and
filter which may have
The one step ahead (filter) estimate of the state E[z(t)|y(t-1), u(t)]. Note: In the case where there is no input u this corresponds to what would usually be called the predicted state - not the filtered state.
The estimated state tracking error P(t|t-1). Again note, this corresponds to the predicted tracking eror not the filtered tracking error. This is NULL for innovations models.
a list of:
The smoother (two sided filter) estimate of the state E[z(t)| sampleT].
The smoothed estimate of the state tracking error P(t|sampleT). This is NULL for innovations models.
