    Regression




    When performing regression analysis on excel with data that has been condensed, should you expand the data before creating the analysis table.

    For example, if a store collected sales in thousands of dollars, but has condensed the data to 1.25, do you have to multiply the data by 1000 to get an accurate regression analysis??

    Well, no you don' i.e.. it's not going change your R or R^2. All you're suggesting is a linear transformation on the data.
