WebJan 15, 2024 · 1 Use the law of total probability. Let F A and F C be the cumulative distribution functions for the weights of adults and children, respectively. If the proportion of adults in the population is p, then P ( X ≤ x) = P ( X ≤ x ∣ Adult) ⋅ P ( Adult) + P ( X ≤ x ∣ Child) ⋅ P ( Child) = p F A ( x) + ( 1 − p) F C ( x).

The assumption behind BMA is that all of the observations come form one of the two models, but we do not know which. Therefore, we weight the forecasts by the probabilities we assign to each of the models. pella brown paint codeWebLet's say I have two probability distributions: f ( x b), g ( x c) b and c are discrete events while x is a continuous variable, i.e., when the button b is pressed there is some distribution for the amount of rain fall the next day, x.
