Formula:
To calculate the linear regression line y = mx + b for a set of n data points (xi, yi), we use the following formulas:
- Slope (m):
m = (nΣxy - ΣxΣy) / (nΣx2 - (Σx)2) - Y-intercept (b):
b = (Σy - mΣx) / n
Where:
n = number of data points
Σx = sum of all x values
Σy = sum of all y values
Σxy = sum of (x * y) for each data point
Σx2 = sum of (x2) for each data point
