Expects a list of Float-tuples, where the first element is the x- and the second element is the y-coordinate of a point. It returns a linear function, that gets a Float and emits new values.

vals = [(0, 0), (1, 0.5), (2, 1), (3, 1.5)]
regressionFunction = regression vals


regressionFunction 4 == 2

Creates a list of tuples with forecasted values. The first parameter indicates how many values.

Please note that this function expects to get a sorted list of points. It will create a range based on the last point.

vals = [(0, 0), (0.5, 0.25), (1, 0.5), (3, 1.5)]


forecast 3 vals == [(4, 2), (5, 2.5), (6, 3)]
