I am fitting several models of the form..
glm(DV ~ I(1/IV), family = Gamma(link = "log")
.. and am looking for ways to compare the models obtained for different variables. I am wondering if the alpha value is of any practical use?
For the three plots below the alpha values are 17.85, 9.03 and 6.27. Do these values contain any information that helps me to interpret my data, or to compare the different variables?
