How to calculate regression analysis
It depends on what your doing, lets just say you want to compare two curves to the same data. First off save the fitted valurs from each model in the worksheet, which you can do by checking the "fits" in the storage dialog. Save the fits for all models you want to compare which I call fit1 and fits 2.
Then you create a scaterplot and display the
Following pairs, original response and predictor data. Fits 1 predictor data fits 2 predictor be sure to check overlaid on the same graph on the multiple graphs dialog. After you create a graph you need to teek it by adding connect lines. Click on the data point on the scatterplotin the menu choose, edit> Add> data display "connect line". This will connect lines to all your datasets, unfortunately you don't want that don't sweat it easy fix to make that go bye bye slowly double click on the connect lines on the original data, which selects the specific connect line, if you do it to fast it will bring up the dialog to edit all connect lines so slowly double click you know like a finger spasm lol. Anyways right click and choose edit connect lines choose custom scroll up and choose none and thats it tour done. Hope this helped
