   Proposal Description:
   <textarea name="description" rows="12" cols="85" wrap="virtual" readonly>My research works are mainly about the biostatistics methods for longitudinal     data. This data would be used as a test data set for my work on the models for    longitudinal data in diagnostic tests. My primary aim is to test the              performance of a new model with the NACC data. Then, I want to make a             comparison between my model and models already proposed. Finally, I also want     to explore if there will be any new clinical or psychological index or their      combinations which would be useful in the early diagnose of Alzheimer disease     and other dementia disease.                                                       1. The data will be used as a test data in the research works about the           statistical methods for diagnostic test.                                          2. To discuss the difference between the chinese and non-chinese AD patients.     3. To explore potential biomarkers for the early diagnosis of AD. </textarea>
