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.
Dr. Tatjana Miljkovic is an Assistant Professor of Practice in the
Department of Statistics at North Dakota State University (NDSU), USA. She
earned her Bachelor Degree in Mechanical Engineering from University of
Belgrade, Serbia, M.S. in Applied Mathematics from University of Illinois
in Urbana .Champaign, USA, M.B.A. and Ph.D. in Applied Statistics from
NDSU. Prior to joining faculty at NDSU, Dr. Miljkovic worked for 12 years
in the industry sector. Her research interests include mixture modeling,
application of the EM algorithm, and Bayesian statistics.
