Parameter Estimation under Constraints for Multivariate Normal Distributions with Incomplete Data.
Zoppe, Alice; Buu, Yuh-Pey Anne; Flury, Bernard
Journal of Educational and Behavioral Statistics, v26 n2 p219-32 Sum 2001
Presents an application of the EM-algorithm to two problems of estimation and testing in a multivariate normal distribution with missing data. The two models are tested applying the log-likelihood ratio test. Solves the problem of different and nonmonotone patterns of missing data by introducing suitable transformations and partitions of the data matrix. (Author/SLD)
