For a discussion on the incorporation of computer algebra systems (CAS), see Flynn et al [1].One technique that can now be done, almost mindlessly, is the line of best fit. Both the graphing calculator and the Excel spreadsheet produce models for collected data that appear to be very ...
The regression line is sometimes called the “line of best fit” because it is the line that fits best when drawn through the points. It is a line that minimizes the distance of the actual scores from the predicted scores. Company
I have about 50000 points with x,y,z data spread in 3 coloumns in excel. I have managed to create a plane of best fit. (by creating a comma delimited file, importing it, setting each column as a variable, then using the SFTOOL function. This gives me a plane of best fit through ...
