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. So the expanded form of β T X is:-. ln ( O) = β 0 + β 1 x 1 + β 2 x 2 + ⋯ + β n x n. So the real use of this, as I have understood it, is to be able to interpret the coefficients easily while ...
