Title: Multivariate mixed response model with pairwise composite-likelihood method Authors:  Xin Gao - York University (Canada) [presenting]
Abstract: In clinical research, study outcomes usually consist of various patients' information corresponding to the treatment. To have a better understanding of the effects of different treatments, one often needs to analyze multiple clinical outcomes simultaneously. At the same time, the data are usually mixed with both continuous and discrete variables. We propose the multivariate mixed response model to implement statistical inference based on the conditional grouped continuous model through a pairwise composite-likelihood approach. We demonstrate the validity and statistical power of the multivariate mixed response model through simulation studies and clinical applications. This composite-likelihood method is advantageous for statistical inference on correlated multivariate mixed outcomes.
