    Who all has started to study for the Spring sitting?

    Doing problems for the Brosius paper. Using CF/RF. In their solutions, on the video and in the Excel, they do the least squares by calculating X-bar, y-bar, etc. and get a and b. But in excel, there is the LINEST function that would simply crank out a and b in an instant. Would we be dinged for using that? Is there some benefit for calculating all of the values?



    I recently took 7 and recall trying to use the LINEST function in the TBE environment. For some reason, it only produces one of the parameters (either a or b) and not both. I would imagine you wouldn’t be dinged but I can’t say for sure given there’s no guidance and will be no further examiner’s reports.
