Marginal Distribution

Definition(s)


Marginal Distribution

statistical distribution (probability) of the occurrence of a variable A that is obtained by integrating over all values of the other variables B, C,

NOTE The marginal probability of A for all values of B, C, … is written as P(A). The concept is applicable to metocean parameters, as well as to actions and action effects.

EXAMPLE When considering wave conditions, A can be the individual crest elevation for all mean zero-crossing periods B and all significant wave heights C, occurring at a particular site.
