Correlation Analysis
The correlation analysis procedure described in Estimating Impulse Responses is implemented in the function impulse
.
This function plots the estimated impulse response. Adding an argument 'sd' as in
it also marks a confidence region corresponding to (in this case) three standard deviations. The result can be stored and replotted.
An alternative is the command step
that plots the step response, calculated from the impulse estimate.
