Staiger and Stock (1997) suggested the rule of thumb that, in the n = 1 case, instruments be deemed weak if the first-stage F is less than ten. They motivated this suggestion based on the relative bias of TSLS.

WebSep 23, 2013 · Staiger and Stock (1997) furthered this research agenda, formalizing the relevant asymptotic theory and recommending the now ubiquitous “rule-of-thumb” measure: a first-stage partial-F test of less than 10 indicates the presence of weak instruments.
