👉 In statistics and data analysis, a "polar" is a type of statistical measure used to compare two variables. It involves using the angle between two vectors that represent the variables in question.
For example, if we have two variables X and Y with unit vectors x_i and y_i respectively, we can use polar coordinates to describe their relationship as follows:
X = r
(cos(theta) + i sin(theta))
Y = s
(cos(theta) - i sin(theta))
