In probability and statistics, a compound probability distribution (also known as a mixture distribution or contagious distribution) is the probability distribution that results from assuming that a random variable is distributed according to some parametrized distribution, with (some of) the parameters of that distribution themselves being random variables.
The way it is done there is that we have two approximately Normal distributions (e.g., p1 and p2, for RR), and we wish to calculate their ratio. [ b ] However, the ratio of the expectations (means) of the two samples might also be of interest, while requiring more work to develop.
The probability distribution of the sum of two or more independent random variables is the convolution of their individual distributions. The term is motivated by the fact that the probability mass function or probability density function of a sum of independent random variables is the convolution of their corresponding probability mass functions or probability density functions respectively.
The compound distribution, which results from integrating out the inverse scale, has a closed-form solution known as the compound gamma distribution. [ 22 ] If, instead, the shape parameter is known but the mean is unknown, with the prior of the mean being given by another gamma distribution, then it results in K-distribution .
A product distribution is a probability distribution constructed as the distribution of the product of random variables having two other known distributions. Given two statistically independent random variables X and Y, the distribution of the random variable Z that is formed as the product = is a product distribution.

The miracle of compounding can turn a mere $1,000 into millions of dollars -- or it can just strengthen your savings account via compound interest.
Consider if you want a withdrawal at 59½ or by age 73, when there are mandatory distributions on your 401(k). If you’re younger than 59½, see if you can qualify for an exception. Impact.
