Hi, I have a problem with the ordered probit model -polr function
(library MASS). My independent variables are countinuos.
I am not able to understand two main points:
a) how to calculate marginal effects
b) how to calculate the relative importance of each independent
variables
If required i will attach my model output.
It is a great puzzle to me that people think that the output of a
statistical program can be interpreted without a clear and complete
description of the input.
