odotusarvovektori
odotusarvovektori is a term used in probability theory and statistics. It refers to a vector where each element is the expected value of a random variable. In simpler terms, if you have several random variables, an odotusarvovektori is a list containing the average outcome you would expect for each of those variables.
The expected value of a single random variable represents the weighted average of all possible outcomes, where
This concept is particularly useful in multivariate analysis, where we often work with datasets that have multiple
Mathematically, if X = [X1, X2, ..., Xn] is a vector of random variables, then its odotusarvovektori, often
