Webb17 aug. 2024 · B ayesian inference works by seeking modifications to the parameterized prior probability distributions in order to maximise a likelihood function of the observed data over the prior parameters. So what happens to the expected posterior in regions where we have missing sample data? Webb8 nov. 2012 · In the Bayesian approach, the data are supplemented with additional information in the form of a prior probability distribution. The prior belief about the parameters is combined with the data's likelihood function according to Bayes theorem to yield the posterior belief about the parameters.
