Fitted curve equation

WebThe accuracy of the line calculated by the LINEST function depends on the degree of scatter in your data. The more linear the data, the more accurate the LINEST model.LINEST uses the method of least squares for determining the best fit for the data. When you have only one independent x-variable, the calculations for m and b are based on the following … A log transformation allows linear models to fit curves that are otherwise possible only with nonlinear regression. For instance, you can express the nonlinear function: Y=eB0X1B1X2B2 In the linear form: Ln Y = B0 + B1lnX1 + B2lnX2 Your model can take logs on both sides of the equation, which is the double-log form … See more The fitted line plot below illustrates the problem of using a linear relationship to fit a curved relationship.
