Denny Sanford School of Social & Family Dynamics Arizona State University Tempe, AZ 85287-3701 (480) 956-9209 (office) yxia@asu.edu Education 2016 Ph.D., Department of Educational Psychology and Learning Systems, Florida State University. Major: Measurement and Statistics. Supervisor: Dr. Yanyun Yang. Yan Xia (2016). Investigating the chi-square-based model-fit indexes for WLSMV and ULSMV estimators. Unpublished doctoral dissertation. 2015 M.S., Department of Statistics, Florida State University. Major: Statistics. 2010 B.S., Department of Psychology, Peking University. Major: Psychology. Certification 2015 Certificate in SAS Programming and Data Analysis, Department of Statistics, Florida State University and SAS Institute. Research Interests My research has been focused on the analysis of ordered categorical data, missing data, nonnormal data, and contaminated data. My research interests surround these difficult data types in structural equation modeling and item response theory, intertwined with diverse topics such as goodness-of-fit evaluation, dimensionality assessment, and reliability. Professional Experience 2016 Present Postdoctoral Research Fellow, Measurement & Statistical Analysis, T. Denny Sanford School of Social & Family Dynamics, Arizona State University. 2014 2016 Statistical Consultant, College of Education, Florida State University.
