Coariance Calculus Function

Description

This function calculates the covariance of two vectors of numbers.

Usage

covariance_(x,y)

Arguments

x

Should be a vector

y

Should be a vector

Details

To calculate the covariance, the user should give two vectors of numbers. The result is a measure of the joint variability of two vectors of numbers. The covariance formule is the following:

Value

Numeric, the covariance of two vectors of numbers.

Note

A vector is created by c(), like c(1,2,3,4,5) creates a vector with the numbers: 1,2,3,4,5

Examples

    #data creation
    data = c(1,4,3,3,2,5,7,12,1,2,3,12)
    data2 = c(1,2,4,4,6,5,11,2,10,5,6,1)
    covariance_(data, data2)
