NettetThe matrix of regressors X is n×K, where n is the number of observations. Some of the regressors are endogenous, so that E(Xiui) =0. We partition the set of regressors into [X 1 X 2], with the K 1 regressors X 1 assumed under the null to be endogenous and the K 2 ≡ (K − K 1) remaining regressors X 2 assumed exogenous, giving us y =[X 1 X NettetIf e.g. one has an equation of 4 variables for 2010-2024 plus one of them lagged by 3 years, there are again 6 coefficients to estimate, but the shortest time series is from … fimfárum 3 online
