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:

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)
