how to make an exponential regression equation. The model with the higher R-squared is the better fit. For R1 the array containing the y values of the observed data and R2 the array containing the x values of the observed data GROWTHR1 R2 x EXP a EXP b x where EXP a and EXP b are as defined from the LOGEST output described above or alternatively from the Regression data analysis.

Next enter your regression model like y_1mx_1b You can also long-hold the colored icon and make the points draggable to see how their values change the equation. After you have added the three. Given a set of data perform exponential regression using a graphing utility.
R2 05878 Exponential Regression Curve.
We use the command ExpReg on a graphing utility to fit an exponential function to a set of data points. Next add 3 more columns to your table. Predicted variable dependent variable slope independent variable intercept. The Coefficients part of the output gives us the values that we need in order to write the regression equation.
