WebBayesian Inference (cont.) Suppose you are uncertain about something. Then your uncer-tainty is described by a probability distribution called your prior distribution. Suppose you obtain some data relevant to that thing. The data changes your uncertainty, which is then described by a new prob-ability distribution called your posterior distribution.
