The SShapedPositive lookup-function is a point symmetric, s-shaped growth function with respect to the origin (0,0) that has a positive slope. The curve has two parameters: An upperBound (lowerBound = -upperBound) and a slope s which is given as a positive number.
The output y is obtained by the following formula:
