新手第一次提问,希望各路大神多多指教!
本人是大四狗一枚~理论知识有点匮乏。以前听说过聚类分析,但是从来没有用过, 第一次看到LCA更觉得不理解。请各位大神帮忙翻译以下这句话是什么意思啊?
Withmultivariate mixture estimation, observed data for multiple continuousvariables are assumed to derive from a mixture of two or more underlyingmultivariate-normal distributions. The continuous data version of LCA, latentprofile analysis, is a restricted version of multivariate mixtureestimation--the constraints are that measures are assumed uncorrelated withineach distribution.
找了好多资料都是英文的感觉好难呀,如果能够用中文给我指点一下将不胜感激!
