Web3.2. Relationship with Cragg–Donald statistic. With g endogenous variables, the minimum eigenvalue of the Cragg–Donald statistic, τ min, is a test for H 0:rank(Π) = g − 1 against the alternative H 1:rank(Π) = g. For the two-variable model, this null is of course equivalent to H 0:π 1 = δπ 2. The Cragg–Donald test is based on the ... WebJun 25, 2024 · 2.
