covarPopStable

Calculates the value of the population covariance:

$$\frac{\Sigma{(x - \bar{x})(y - \bar{y})}}{n}$$

It is similar to the covarPop function, but uses a numerically stable algorithm. As a result, covarPopStable is slower than covarPop but produces a more accurate result.

Syntax

Arguments

• x — first variable. (U)Int*, Float*, Decimal.
• y — second variable. (U)Int*, Float*, Decimal.

Returned Value

• The population covariance between x and y. Float64.
