WebAnd, the last equality just uses the shorthand mathematical notation of a product of indexed terms. Now, in light of the basic idea of maximum likelihood estimation, one reasonable way to proceed is to treat the " likelihood function " \ (L (\theta)\) as a function of \ (\theta\), and find the value of \ (\theta\) that maximizes it. WebA covariate-dependent approach to Gaussian graphical modeling as described in Dasgupta et al. (2024). Employs a novel weighted pseudo-likelihood approach to model the conditional dependence structure of data as a continuous function of an extraneous covariate.

A marginal likelihood just has the effects of other parameters integrated out so that it is a function of just your parameter of interest. For example, suppose your likelihood function takes the form L (x,y,z). The marginal likelihood L (x) is obtained by integrating out the effect of y and z.
