We derive a formula for the probability distribution of a random variable if it is statistically dependent on other random variables of a stochastic system supposing that it is in its maximum entropy state. We
If you’re great with equations, that’s probably all you need to know. It tells you how to find a marginal distribution. But if that formula gives you a headache (which it does to most people!), you can use afrequency distribution tableto find a marginal distribution. Amarginal distri...
The probability function P(X = x, Y = y), which we will write in the simpler form P(x, y), is given by a formula of the type presented in Eq. (23.18), with N (the number of events) equal to 2 and with the three individual-event probabilities pa, pb, and pc. The number ...
Formultivariate distributions, formulae similar to those above apply with the symbolsXand/orYbeing interpreted as vectors. In particular, each summation or integration would be over all variables except those contained inX. See also Joint probability distribution Wasserstein metric References ^Trumpler and...

A closely related probability is thesurvival probability, which is the complement of the cumulative probability and is reported as S(t)=P{T>t}=1−PDcumulative(t) The following recursive formula shows the relationship between the conditional PDs and the survival probability: ...

Probability theory tells us that two binary variables are statistically independent if the odds ratio is equal to unity, i.e., ad/bc = 1. Due to the simple formula of its standard error, the logarithm of the odds ratio is sometimes preferred over the ordinary odds ratio. However, the ...
