Pseudo R2 In R Interpretation. If it were me I would ignore it. The interpretation of McFaddens pseudo R 2 between 02-04 comes from a book chapter he contributed to.
Oct 20 2011 These are pseudo R-squareds because they look like R-squared in the sense that they are on a similar scale ranging from 0 to 1 though some pseudo R-squareds never achieve 0 or 1 with higher values indicating better model fit but they cannot be interpreted as one would interpret an OLS R-squared and different pseudo R-squareds can. The formulas and rationale for each of these is presented in Appendix A. .
R-squareds some never achieve 0 or 1 and higher.
One such index outlined by Maddala 1983 and Cox and Snell 1989 is. In the case of logistic regression usually fit by maximum likelihood there are several choices of pseudo-R 2. Psuedo r-squared for logistic regression. Nagelkerkes R 2 2 is an adjusted version of the Cox.
