I found that I could use : vglm(formula, family,.., data), but I dont know how to interpret the output!!! min 1Q Median 3Q Max elogit (lambda) -.66 -.61 -.46 -.06 35.33 log(theta) -10.2 -.02 .11 .64 1.2 coefficients: value std t.value intercept:1 .76 .019 39.32 intercept:2 1.02 .02 39.88 sex .55 1.2 16.00 log-likelihood -990.83, I dont know what is the exactly meaning of these two intercept?
