Overview

The function returns the covariance of two arrays.

Syntax

array.covariance(id1, id2, biased) → series float

Parameters

Name	Type	Description
id1	array<int/float>	An array object.

Returns

The covariance of two arrays.

Remarks

• If biased is true, function will calculate using a biased estimate of the entire population, if false - unbiased estimate of a sample. Returns na if both arrays are empty.

Examples

Example 1

//@version=6
indicator("array.covariance example")
a = array.new_float(0)b = array.new_float(0)
for i = 0 to 9
array.push(a, close[i]) array.push(b, open[i])
plot(array.covariance(a, b))
