Given my "acknowledged statistical ignorance", I tried to find a *solution *in this forum... And this is not primarily a statistical issue, it is an issue about the Hausman test in the R environment.
I cannot imagine, no one in this forum has ever done a Hausman test on OLS regressions. I read in the systemfit package and found only this example referring to 2SLS and 3SLS regressions: data( "Kmenta" ) eqDemand <- consump ~ price + income eqSupply <- consump ~ price + farmPrice + trend inst <- ~ income + farmPrice + trend system <- list( demand = eqDemand, supply = eqSupply ) ## perform the estimations fit2sls <- systemfit( system, "2SLS", inst = inst, data = Kmenta ) fit3sls <- systemfit( system, "3SLS", inst = inst, data = Kmenta ) ## perform the Hausman test h <- hausman.systemfit( fit2sls, fit3sls ) print( h ) -- View this message in context: http://r.789695.n4.nabble.com/Hausman-test-in-R-tp4647716p4647774.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
