Covariance as inner product
$begingroup$
Why is covariance considered as inner product if there is no projection of one vector onto another?
Right now I perceive this as just a multiplication of $x$ segment of vector($x_i - bar{x}$) and $y$ segment($y_i - bar{y}$) of the same vector in order to understand direction of relationship.
