Engle–Granger test क्या है?

अन्य नाम: Engle--Granger test

Definition 20.7 Quantitative Methods · अध्याय 20 — Multivariate Series and Cointegration

The Engle–Granger test regresses one variable on the others in levels and applies a Dickey–Fuller test to the residuals, with critical values that account for the estimated coefficients.

Null distributions of the Dickey–Fuller statistic for one random walk and for the least-squares residual of one random walk regressed on two others, from 4 000 simulated samples of 1 000 days; the dashed lines are their 5% points, -2.92 and -3.75. Data: the chapter’s tutorial, seeded.
