Standard Linear Regression. LINREG is a rolling regression of one variable. A
Standard Linear Regression is between two or more variables.

Calculation:
Default Inputs:
length=14
x = [1, 2, ..., n]
x_sum = 0.5 * length * (length + 1)
x2_sum = length * (length + 1) * (2 * length + 1) / 6
divisor = length * x2_sum - x_sum * x_sum
