I have a dataset relating two variables to a result, as shown in the image below.
In the image Variable 1 is held constant, and plotted against different values of Variable 2, and the result is shown. I have several entries for Variable 1 (though I can have as many intervals as I like. What I'm trying to do is determine an equation that gives Result as a function of Variable 1 and 2. i.e.
Result (Var1, Var2) where 0 >= Variable 1, Variable 2 <= 100
It seems like it should be a simple thing to do, but I'm not quite sure how to start.
