Proc autoreg stationarity

WebbTheory for the Cochrane-Orcutt Procedure. A simple regression model with AR errors can be written as. ( 1) y t = β 0 + β 1 x t + Φ − 1 ( B) w t. Φ ( B) gives the AR polynomial for the errors. If we multiply all elements of the equation by Φ ( B), we get. Φ ( B) y t = Φ ( B) β 0 + β 1 Φ ( B) x t + w t.

WebbTesting causality, in the Granger sense, involves using F -tests to test whether lagged information on a variable Y provides any statistically significant information about a variable X in the presence of lagged X. If not, then " Y does not Granger-cause X ." There are many ways in which to implement a test of Granger causality. WebbFor studies that reported the statistical software used (70%, N=958), a considerable number performed their analysis using either SAS (37%, N=353) or STATA (36%, N=348) statistical software. PROC AUTOREG in SAS is the most commonly reported software package (15%, N=52) among the SAS users. Discussion
