My key independent variable in my regression (logit) is the product's degree of spanning. I have two different measurement methods for this factor. And how can I statistically compare?
Yan Fu I don't understand if you want to compare the measurement methods directly or their use in two different regression models Or for amount of collinearity introduced or......... Please advise. Best, D. Booth
David Eugene Booth Hi, thanks for your reply. I want to compare the measurement methods directly to show which measurement method is better. And the regression model is a logit model. I also wonder if the log-likelihood of the model can be used to compare the two measurements?
