Abstract: The present paper deals with the estimation problem for zero mean value AR(p) model with one date or two continuous data missed. The paper is based on the EM algorithm. By using the iterative method, we have obtained the estimated values of parameters.

Key words: likihood function, EM algorithm, conditional probable density
