Test for difference, split sample MNL, Poe test
Posted: 15 Sep 2021, 20:10
Hi everyone,
I am rather new to R and Apollo, however, based on your examples I managed to got an MNL estimation for my data set running. I did a split sample approach and for each sample I estimated the parameters. Now I wanted to see, if my estimations for the attributes differ significantly between the two samples. For the analysis I wanted to use the Poe test (R Package "mded"), which measures the difference between two independent or non-independent empirical distributions and should return a significance level of the difference.
However, from my understanding, for this test I need to have the individual estimations for the respondents for each attribute. And currently I have really no idea, how to get these from my MNL estimations. Is there any chance that you could help me out on this and give me a hint, how to get the attribute estimations for each individual? Or is that not necessary?
I am really looking for you answer! Thank you very much in advance!
