# Marginal distribution functions of x and y

It gives the probabilities of various values of the variables in the subset without reference to the values of the other variables. Joint Distributions Basic Theory Joint and Marginal DistributionsAs usual, we start with a random experiment with probability measure $$\P$$ on an underlying sample space. Suppose now that $$X$$ and $$Y$$ are random variables for the experiment, and that $$X$$ takes values in $$S$$ while $$Y$$ takes values in $$T$$.

We can think of $$(X, Y)$$ as a random variable taking values in (a subset of) the product set $$S \times T$$. The purpose of this section is to study how the distribution of $$(X, Y)$$ is related to the distributions of $$X$$ and $$Y$$ individually. Kostenlose Lieferung ab EUR 29 BestellwertDurchschn.
