WebDec 14, 2024 · The Cragg-Donald statistic is proposed by Stock and Yugo as a measure of the validity of the instruments in an IV regression. Instruments that are only marginally valid, known as weak instruments, can lead to biased inferences based on the IV estimates, thus testing for the presence of weak instruments is important.
