Partial (sufficient) dimension reduction arises when the predictors naturally fall into two sets X and W, and pursues a partial dimension reduction of X. Though partial dimension reduction is a very general problem, only very few research results are available when W is continuous. To the best of our knowledge, these methods generally perform poorly when X and $\\W$ are related, furthermore, none can deal with the situation where the reduced lower-dimensional subspace of $\\X$ varies with W. To address such issue, we in this paper propose a novel variable dependent partial dimension reduction framework and adapt classical sufficient dimension reduction methods into this general paradigm. The asymptotic consistency of our method is investigated. Extensive numerical studies and real data analysis show that our Variable Dependent Partial Dimension Reduction method has superior performance comparing to the existing methods.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Speaker: Dr. Xuerong Wen from Missouri University of Science and Technology Date and Time: Friday, October 15, 2021, 11:15am-12:15pm via Zoom.
