What is the formula to calculate sensitivity coefficient and what is the threshold for display tasks of risks with very little sensitivity coefficients?

RiskyProject uses Spearman rank order correlation coefficient to calculate project parameter’s sensitivity to variance in inputs such as cost or risk events. This formula returns a coefficient that is between -1 and 1. The higher the value the stronger the correlation is between the two variables. Perfect correlation equals 1. Perfect inverse correlation would equal -1.

You can minimize the number of activities or risks in the Sensitivity view by modifying the sensitivity threshold. Any results that have a correlation below the threshold will not be visible. To modify the sensitivity threshold, go to Schedule, Project Options > and modify the value in the Minimum Sensitivity Coefficient box.
