Residual Sum of Squares from Slope

Problem

For simple regression, SSE = Syy - slope * Sxy, where Syy and Sxy are the centered sums.

Given Syy, Sxy, and the fitted slope, return SSE.

Hint

The slope explains part of the total variation.

expected: 2.5

case 2

in: [4,4,1]

expected: 0

case 3

in: [8,0,2]

expected: 8
