Formula:

least-square-regression

Where,

Y = LSRL Equation
b = The slope of the regression line
a = The intercept point of the regression line and the y axis.
X̄ = Mean of x values
Ȳ = Mean of y values
SDx = Standard Deviation of x
SDy = Standard Deviation of y
r = (NΣxy - ΣxΣy) / sqrt ((NΣx2 - (Σx)2) x (NΣy)2 - (Σy)2)
