... then we have two possible models: p = 0.6 and p = 0.2 . (These are similar to the hypotheses that one studies in tests of significance using frequentist methods.) After the three observed jumps, we conclude that there is an 82% chance that the p = 0.6 model is the correct one. In frequentist inferen ...
