Explaining variability in logistic regression
Posted on August 2, 2010 at 9:42am 6 Comments 0 Likes
Hi All,
I have built a logistic regression but I am not able to figure out which goodness of fit measure will help me know 'How much variability of the dependent variable is being explained by the current model'
I have calculated few pseudo r2 to measure this but as we know pseudo r2 is not a good way of measuring.
In addition to this can any one tell me how to calculate McKelvey & Zavoina's pseudo r2
Thanks
Jai
