单词	marginal distribution
释义	marginal distribution Mathematics Suppose that X and Y are discrete random variables with joint probability mass function p. Then the marginal distribution of X is the distribution with probability mass function p₁, where $p_{X} (x) = \sum_{y}^{} p (x, y) .$ A similar formula gives the marginal distribution of Y. Suppose that X and Y are continuous random variables with joint probability density function f. Then the marginal distribution of X is the distribution with probability density function f_X, where $f_{X} (x) = \int_{- \infty}^{\infty} f (x, y) d y .$ Statistics See bivariate distribution.
