Then obtain base-case, best-case, and worst-case NPV and calculate mean NPV and standarddeviation to (roughly) estimate the magnitude of the risk inherent to the project.
The algorithm adopts low pass filter to estimate the background and calculates the standarddeviation to estimate the fluctuation of background to get the local adaptive detection threshold.
