Hi,
I am currently creating an Excel sheet (in Excel 2013) to calculate different methods of forecasting. In one sheet I would like to display the equations (I mean the notation, not the actual Excel function) used in the calculations based on the actual values
to forecast.
I know how to use equation editor quite well to create equations. However what I would like to do is insert in an equation the value of a given cell. For example, consider the following equation that calculates Beta-one:

What I would like to do is show the value of cell A1 as n, the value of C20 as
sigma-t, the value of D20 as sigma-t-squared, etc.
Is that possible?
Regards,
P.
