Now, let us use the RSQ function to find R2 in excel. Write this formula in cell A12. =RSQ(B2:B9,A2:A9) When you hit the enter button you get the value 0.725103502, which is 72% approx. How to Interpret R-Squared The R-Squared value always falls in the range 0.0-1.0 or we ca...
Excel has several built-in functions and tools that make it easy for us to calculatestatistical values. For instance, we can easily calculate the R-squared value in Excel. So the R-squared, often written as r2, allows us to determine how well our data set fits the regression line. Furthe...
The termLeast Squaresrefers to the approach of finding the line that minimizes the sum of squared differences between observed data points and their corresponding predicted values on the line. Essentially, it represents the average trend within the data. By using this line of best fit, we can m...
I believe the exponential smoothing in Excel uses the simple (Brown’s) exponential method. There are other methods that can be more appropriate if the data exhibits trend or seasonality. For the damping parameter (0-1), I suggest you calibrate this value by minimizing the sum of squared err...
