Statistical independence is a concept in probability theory. Two events A and B are statistical independent if and only if their joint probability can be factorized into their marginal probabilities, i.e., P ( A ∩ B) = P ( A) P ( B ). If two events A and B are statistical independent, then the conditional probability equals the ...

A joint probability is the probability of event A and event B happening, P(A and B). It is the likelihood of the intersection of two or more events. The probability of the intersection of A and B is written as P(A ∩ B).

NettetIndependence is a fundamental notion in probability theory, as in statistics and the theory of stochastic processes. Two events are independent, statistically independent, or stochastically independent [1] if, informally speaking, the occurrence of one does not affect the probability of occurrence of the other or, equivalently, does not affect ... Nettet5. mar. 2012 · 5. As far as I'm concerned, the most important distinction is that likelihood is not a probability (of θ ). In an estimation problem, the X is given and the likelihood P ( X θ) describes a distribution of X rather than θ. That is, ∫ P ( X θ) d θ is meaningless, since likelihood is not a pdf of θ, though it does characterize θ to ...
