numerical value of the log likelihood.
Note that some methods compute not the log likelihood itself but instead a related quantity.
To keep the code simple, the logLik
function is nevertheless used to extract this quantity.
When object
is of ‘probed_pomp’ class (i.e., the result of a probe
computation), logLik
retrieves the “synthetic likelihood” (see probe
).
When object
is of ‘bsmcd_pomp’ class (i.e., the result of a bsmc2
computation), logLik
retrieves the “log evidence” (see bsmc2
).
When object
is an NLF objective function, i.e., the result of a call to nlf_objfun
,
logLik
retrieves the “quasi log likelihood” (see nlf
).
