Pseudo-likelihood function
WebThe pseudo-likelihood estimator is a natural estimator for such models, as com- puting the pseudo-likelihood estimator does not require knowledge of the partition function Z n … WebThe pseudo-likelihood method (Besag 1971) offers a different approach to this problem, which surpris-ingly yields an exact solution if the data is generated by a model p(x; ) and n!1(i.e., it is consistent). The goal is to replace the likelihood by a more tractable objective. To do this, we note that: p(x; ) = Y i p(x ijx 1;:::;x i 1) (2) via ...
