Linearly uncorrelated

In probability theory and statistics, two real-valued random variables, $${\displaystyle X}$$, $${\displaystyle Y}$$, are said to be uncorrelated if their covariance, $${\displaystyle \operatorname {cov} [X,Y]=\operatorname {E} [XY]-\operatorname {E} [X]\operatorname {E} [Y]}$$, is zero.

Nettet15. jul. 2024 · Broadly, yes - two random variables may be related in a non-linear way. The simplest example would be where one is directly calculated from the other with a non-linear function, for example Y = X 2. We tend to not say "linearly independent", but we might say that the variables are "linearly uncorrelated" if their correlation coefficient is zero. Nettetthe variables in X 1. This will only be zero if the variables in X 1 are linearly unrelated (uncorrelated. or orthogonal) to the variables in X 2. The correction vector will also be zero if βˆ 2 = 0 i. if X 2. variables have no impact on y. Thus, you can ignore all potential omitted variables that are either
