Nettet3.4 Linear Hypothesis Testing (Wald and F) ... 1.2 How is R Better Than Other Packages? R is much more more exible than most software used by econometricians because it is a modern mathe-matical programming language, not just a program that does regressions and tests. Nettet21. jun. 2024 · 1 Answer. We may test hypotheses on the intercepts of a "polr" object using car::linearHypothesis.default. The method has an argument coef.= which we may feed with the combined coefficients and zetas, giving us correspondence with the already correctly existing vcov. The hypothesis.matrix= we define as a matrix.

A simple regression approach would be lm (hdl ~ 1 + group + weight + group*weight). And then the coefficient for the interaction term group*weight would tell you whether or not there is a significant interaction (i.e., moderation) effect. However, I think we would have a major …
