1 如何找catigorical variables 的collinearity? such as race (white, black,
latino), sex(male,female), education(college or not college graduated),age(<20, 20-40, >40), income (below, above a level) etc.
2. 我在用logistic regression 时， test Deviance and Pearson Goodness-of-Fit
Statistics, the p-value of Deviance is 0.0037, and the p-value of Pearson is
0.0061. Do these mean that the logistic regression is not fitting the data well? What should I do next?
Thanks. | a****m

correlation等等 | d******o

Collinearity diagnostics for logistic regression can use condition index
with variance decomposition methods.
I have a paper discussing about VIF for GLMs It hasn't been published yet. | a*****3

(<20, 20-40, >40), income (below, above a level) etc.

is
data well? What should I do next?
