The exponential regression calculator can be used to fit an exponential function to input data points. The exponential regression equation is: y = a b x y = a^{bx} y = a b x. Where: y y y is the predicted value for the response variable, x x x is the predictor variable,Step 4. You can obtain the equations for exponential, power, and logarithmic regression curves by linearizing the functions. For example, the equation y = ac x can be linearized by taking the natural logarithm of both sides. Doing this yields Ln (y) = Ln (a) + Ln (c)x. This is now linear in the variables Ln (y) and x.A regression was run to determine whether there is arelationship between the diameter of a tree (x, in inches) and the tree’s age (y, in years).
