## FormulasThe estimated slope w₁ and intercept w₀ can be calculated using following formulas. ## Formula 1## Formula 2(derivation: see end of this article) ## Formula 3Coefficient w₁-hat expressed as a product of the correlation between y-values and x-values, and the fraction of standard-deviation of y-values over standard deviation of x-values: ## NoteIn above formulas read the sigma as sum from i=1 to n: |
