Central subspaces are designed to capture all the information for the regression and to provide a population structure for dimension reduction. Here, we introduce the central kth-moment subspace to capture information from the mean, variance and so on up to the kth conditional moment of the regression. New methods are studied for estimating these subspaces. Connections with sliced inverse regression are established, and examples illustrating the theory are presented.<\/jats:p>","DOI":"10.1111\/1467-9868.00330","type":"journal-article","created":{"date-parts":[[2003,5,6]],"date-time":"2003-05-06T15:13:15Z","timestamp":1052233995000},"page":"159-175","source":"Crossref","is-referenced-by-count":121,"title":["Dimension Reduction for the Conditional<i>k<\/i>th Moment in Regression"],"prefix":"10.1093","volume":"64","author":[{"given":"Xiangrong","family":"Yin","sequence":"first","affiliation":[{"name":"University of Georgia , Athens , USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R.
