Tsls statistics
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. In the code below, I have illustrated how one can perform these partial F-tests in R. WebIn a first step you run the first step regression (s) of the TSLS procedure. In our case this is. # First Stage first_stage <- lm (educ~age+exper+expersq+fatheduc+motheduc,data=mydata) In a second step you add the residual (s) from this first step into the original model.
