It doesn't have to particularly accurate - just the general shape, convex w/ one hump, concave w/ two, straight line, etc - would be fine. I could use conditionals for every possible shape: for example, if the slope is positive upto a certain index, and negative after, it's a slope, with the skewness depending on index/list_size .Working of a Concavity Calculator.
