Estimating x1 and x, using the current estimate of n leads to ~$13)= 125-8 and xip) = 125-in(p) g+ &n(P) g +tn(p)' The maximization step then takes the estimated complete data (x:p),xip), 18,20,34) and estimates n by maximum likelihood as though the estimated complete data were the observed data, thus yielding
