Tutorial on Bayesian learning and related methods
... Bayes law is the basis for learning In the urn problem, observing R tells you something about the coin flip but does not tell you if it’s H or T with certainty; The question is then: how “certain” can I be that the flip is a H? Or T ? Bayes’ law allowed us to compute how certain, as a probability, ...

Joint probability distributions
... Note that the covariance depends on the units of measurement. If X is re-scaled by a factor c and Y by a factor k , then Cov[ cX, kY ] = E[ cXkY ] E[ cX ] E[ kY ] = ck E[ X Y ] c E[ X ] k E[ Y ] = ck (E[ X Y ] E[ X ] E[ Y ] ) = ck Cov[ X, Y ] A special case is V[ cX ] = Cov[ cX, cX ] = c2 ...

... What must these probabilities look like for C = 1 to be more probable than its negation? One possibility is for origination events to be so vastly improbable that there probably was just one in the whole time since the earth began. A second possibility is that start-ups and blow-ins are not terribly ...
