The correlation coefficient does not have meaning (is not defined) for most regression models. Check you theory to make sure it exits for the sine regression.
An easy way to verify that, is to use the Command DiagnosticOn, accessible through the catalog [2nd] (CATALOG) . Press [X^-1] (D) to jump to first command that starts with D. Scroll down to DiagnosticOn, select it and press [ENTER]. Calculator replies Done.
Do your sine regression again. If the correlation coefficient has meaning for this type of regression, you will find it with the other statistical variables. You may have to scroll down the statistical variable list to verify the whole contents of the list.
Hope it helps.
Thank you for rating the solution.
