Assuming our data follows an exponential trend, a general equation + may be: We can linearize the latter equation (e.g. y = intercept + slope * x) by taking the log: Given a linearized equation ++ and the regression parameters, we could calculate: A via intercept (ln(A)) B via slope (B) Summary of Linearization TechniquesLog Mode. Enabling log mode changes the strategy that the calculator uses to fit regression parameters. By default, regression parameters are chosen to minimize the sum of the squares of the differences between the data and the model predictions. When log mode is enabled, a transformation that makes the model linear is applied to both the data ...Verify the data follow an exponential pattern. Find the equation that models the data.
