Question

Use three sentences to summerize multinomial distribution, bivariate normal distribution and linear combination respectively.( can be an explanation or the main point of knowledge).

Answer 1

Multinomial distribution, is a generalization of the binomial distribution, which admits only two values (such as success and failure), to more than two possible outcomes.

A bivariate normal distribution is made up of two independent random variables which are both are normally distributed, and they also have a normal distribution when both are added together.

A linear combination is an expression constructed from a set of terms by multiplying each term by a constant and adding the results.
