MoCa vs MMSE project Lead Investigator: Xiaonan Wang Institution : Univ of Washington E-Mail : hnaywxn@163.com Proposal ID : 709 Proposal Description: The purpose of our study is to compare the accuracy of two diagnostic tests in the absence of a gold standard. Specifically, I developed a new statistical method about how to evaluate the accuracy of diagnostic tests with ordinal true disease status in the absence of a gold standard.
