Syntax
>>>> REGRESSION: rho
Parent Command
any third-level command in block > OBSERVATION
Subcommand
none
Description
This command sets the autoregression coefficient rho for a data set. To partially account for time correlations, a first-order autogregressive time series model (AR1) can be applied to the residuals:
The first-order autoregressive should be applied to time series only if the sampling interval is approximately constant. The autoregression coefficient rho can be estimated using command >> REGRESSION.
