WebThe test we propose is a simple one: compute the minimum eigenvalue of the matrix version of the F-statistic in the first stage of TSLS and compare it to a critical value, tabulated below. If the minimum eigenvalue is less than the critical value, conclude that the instruments are weak; otherwise, conclude they are not.1 Both the ...
