regression calculation. To copy a resulting regression formula, press 6(COPY).
k Estimated Value Calculation ( , )
After drawing a regression graph with the Statistics mode, you can use the Run-Matrix mode
to calculate estimated values for the regression graph's
Example
1. From the Main Menu, enter the Statistics mode.
2. Input data into the list and draw the linear regression graph.
