curve fitting multiple variables excel
How do you run a regression in Excel with multiple variables?
From the menu, select "Regression" and click "OK".
In the Regression dialog box, click the "Input Y Range" box and select the dependent variable data (Visa (V) stock returns).
Click the "Input X Range" box and select the independent variable data (S&P 500 returns).
Click "OK" to run the results.How do you curve fitting in Excel?
