But I also had the impression that the Wald value was an approximation as well. > summary(polr(as.factor(RENUCYC) ~ DOCS + PCT65PLS*RANNEY2 + OLDCRASH + FISCAL2 + PCTMETRO + ADMLICEN, data=elaine1)) Re-fitting to get Hessian Call: polr(formula = as.factor(RENUCYC) ~ DOCS + PCT65PLS * RANNEY2 + OLDCRASH + FISCAL2 + PCTMETRO + ADMLICEN, data = elaine1) Coefficients: Value Std.
