| Abstract: | Taking into account the ordinal character of variables,statistical inference for bidirectionally ordinal square contingency tables with missing data is studied by proposing a loglinear model with restrictions.EM algorithm based on the loglinear model is provided for dealing with missing data of bidirectionally ordinal square contingency tables and an example has been given.The result indicates that the problem is solved finely. |
