The distribution of standardised ML estimate of mean in bivariate normal sample with monotone pattern of missing data is considered and compared with the distribution of standardised complete case estimate. The plots of pdf’s and calculations of cdf’s are given for chosen small sample sizes.
bivariate normal distribution, missing data, maximum likelihood estimate.
