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 发帖数: 693 | 2 collinearity 应当依据linear model, 他们有很多的技术指标,比如,VIF,或者是
correlation等等 | d******o 发帖数: 59 | 3 see paper:
http://www.stat.lsu.edu/faculty/marx/CollinCSDA.pdf
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 发帖数: 601 | 4 你原创的?
with variance decomposition methods.

(<20, 20-40, >40), income (below, above a level) etc.
Fit
is
data well? What should I do next?
