An alternative for robust estimation in Project Management

► The U-TSP and U-GBP distributions are presented as alternatives to the Uniform-Beta distribution. ► Generally, the classical U-TSP and U-GBP distributions have higher kurtosis than the classical U-BETA. ► The cdf of the U-TSP and U-GBP distributions present more possibilities by allowing to vary n. ► The elicitation procedure proposed allows us to increase the accuracy of the estimation.
