Hello, I'd like to ask: going on from Richard McElreath's coursework in which he says(my paraphrase) basically that the constancy with which a parameter appears satisfactory with respect to its standard error over a series of different models is a good measure of its usefulness, where is the "coeftab" function in R that he uses to bring these up? It doesn't come up with anything I try? Secondly, when R prints asterisks instead of parameter standard errors, is there a standard answer -s [[alternative HTML version deleted]]
