Hi,
I have a 4-factor regression that looks like
excess return = Market premium + SMB + HML +MOM
Monthly data 2005-2015, 120 observations.
I would like to graph the beta values over time, aka do a "rolling regression" in order to detect if the beta values are changing over time.
How can I perform this in excel? I have heard something about using the Linest function?
Appreciate all help! thanks.
