A semiparametric two-sample homogeneity test with nonignorable nonresponse using callback data

Xinyu Wang, Tao Yu, Chunlin Wang +1

Testing the homogeneity of two distributions is fundamental in statistics, but classical procedures may fail under nonignorable nonresponse. In many surveys, callback data record r…
