WebWell, a predicted probability is, essentially, in its most basic form, the probability of an event that is calculated from available data. What are predicted probabilities in logistic … WebPredictive probabilities can be computed via the law of total probability, as weighted averages over possible values of $\theta$. However, even when conditional distributions of data given the parameters are well known (e.g., Binomial($n$, $\theta$)), marginal distributions of the data are often not.
