ESTIMATING INCOMPLETE INFORMATION IN THE DATA USING EM ALGORITHM
Expectation Maximization (EM) algorithm is a powerful tool for recovery of missing data and estimation of incomplete information in the data. A novel application of the EM algorithm is proposed for modeling censored regression. Parameter estimates, variability assessment, and model selection are summarized in multiple regression settings using a normal model. New formulas for measuring model utility and model diagnostics are derived based on the EM algorithm. They include reconstructed coefficient of determination, Jackknife residuals, test for the outlier detection, and influence diagnostics based on one-step deletion method. The proposed methodology is tested using three real data sets.
