Posterior predictive · QBar is the input

Horizontal position is probability p, not x. Tap/click anywhere: the current predictive inverse CDF turns that p into an observation x, then Bayes updates. Orange dots are past observations reprojected into the current predictive.

Tap/click a probability position; QBar converts it through the predictive inverse CDF into the next observation.
