Inference 50, No.3, 373-378 (1996).} \itemab Summary: This paper illustrates the use of quasi-likelihood methods of inference for hidden Markov random fields. These are simple to use and can be employed under circumstances where only the model form and its covariance structure are specified. In particular they can be used to derive the same estimating equations as the EM algorithm or change of measure methods, which make full distributional assumptions. \itemrv{~} \itemcc{} \itemut{quasi-likelihood methods of inference; hidden Markov random fields; covariance structure; estimating equations; EM algorithm; change of measure methods} \itemli{doi:10.1016/0378-3758(95)00064-X} \end
