Web28 Jun 2024 · Taking the logarithm turns the multiplication into addition: l o g ( x y) = l o g ( x) + l o g ( x). The differentiation is much easier. The maximum of f ( x) is the same as the maximum of l o g ( f ( x)), so we prefer the function with the easier derivative. We don't care what the maximum of the likelihood function is. Web24 Mar 2024 · Keep in mind that doing regression on logged data will change the form of the equation of the fit from y = a x + b to l o g ( y) = a l o g ( x) + b (or alternatively y = x a e b ). Beyond this scenario, I would say it never hurts to try graphing the logged data, even if it doesn't make the residuals more homoscedastic.

Web3 Apr 2024 · So that algebraic manipulation is basically taking a natural log of the latest form of O ( e β T X) i.e. ln ( O) = ln ( e β T X) = β T X.
