Web27 Jan 2024 · The problem that arises in the parameter estimation of his model is MLE cannot find an implicit analytical solution, so it is necessary to apply iteration methods in the form of Fisher Scoring with the iteration β ^ f s (r + 1) = β ^ f s (r) + I (β ^ f s (r)) − 1 g (β ^ f s (r)), for r = 0,1, 2, … and Berndt Hall-Hall-Hausmann (BHHH) using iteration β ^ b h h (r + 1) … WebDescription. This is the main interface for the maxLik package, and the function that performs Maximum Likelihood estimation. It is a wrapper for different optimizers returning an object of class "maxLik". Corresponding methods handle the likelihood-specific properties of the estimates, including standard errors.

WebThe opt-level setting controls the -C opt-level flag which controls the level of optimization. Higher optimization levels may produce faster runtime code at the expense of longer compiler times. Higher levels may also change and rearrange the compiled code which may make it harder to use with a debugger. The valid options are: 0: no optimizations
