REGWUTEST: RATS procedure to perform Wu (or Durbin-Wu-Hausman) specification test on regression


  • Tom Doan

    () (Estima)


RegWuTest performs a Wu (or Durbin-Wu-Hausman) specification test on a regression just estimated by instrumental variables. Because it works off the last regression, there are no parameters.
