(When the marginal is the uniform distribution on the circle -- that fully determines it, but it has no density function.) As you go through, note that the same analysis applies mutatis mutandis to finding the distribution of any proper subset of the coordinates, from through of them.

What

If more than one random variable is defined in a random experiment, it is important to distinguish between the joint probability distribution of X and Y and the probability distribution of each variable individually. The individual probability distribution of a random variable is referred to as its marginal probability distribution. In general, the marginal probability distribution of X can be determined from the joint probability distribution of X and other random variables. http://www.stat.yale.edu/~pollard/Courses/241.fall2005/notes2005/Joint.pdf prolight hub https://wilhelmpersonnel.com

Calculate marginal distribution from joint distribution in Python

Given a known joint distribution of two discrete random variables, say, X and Y, the marginal distribution of either variable – X for example – is the probability distribution of X when the values of Y are not taken into consideration. This can be calculated by summing the joint probability distribution over all values of Y. Naturally, the converse is also true: the marginal distribution can be obtained for Y by summing over the separate values of X.

NettetFrom the perspective of a given distribution, the parameters are constants, and terms in a density function that contain only parameters, but not variables, are part of the normalization factor of a distribution (the multiplicative factor that ensures that the area under the density—the probability of something in the domain occurring— equals 1).
