    does this only work for linear regression? i tried to plot a function for my list but there wasn’t the option to plot with “stat.regeqn” ?

      Works for all regression types. As soon as you complete the regression analysis, the equation will be stored in stat.regeqn.
      Things to check:
      1. Make sure you have comleted the corresponding regression analysis already (menu item)
      2. You are in the same problem. Variables are not shared across problems.
      3. There are various conditions that must be met for regression to work, depending on the selected regression, however you will recieve a corresponding error message if it isn't working. For example: "Dimension Error" - Attempted to do cubic regression with only 3 data points, not enough data to perform regression.

    can u bring a function from the calculator to the graph section? I didn't manage to copy past between windows. plus can u integral piecewise function?

      Graph and equation that is on the calculator application - Yes! On the calculator, select the equation then press Ctrl + Menu (same as right click of a mouse on a computer) and you should see the option to graph. The graph will appear on the same page, press Ctrl + 6 to ungroup the pages.
      Integrals of piecewise function, of course, easier if you define your piecewise function as f(x) or g(x) etc... and then integrate f(x), g(x) etc.
