WebbThe generalized Bayesian model was developed by Cai et al. for uncertainty analysis of single-value NPFs based on a Bayesian formula and generalized probability density function (GPDF) . The Bayesian formula is an effective method for uncertainty analysis and is commonly used in probabilistic forecasting [49,50]. Webbanalysis phase needed to identify key drivers of output uncertainty (Mishra & Knowlton 2003). The second step, i.e. characterization of uncertain inputs using probability distributions, is a key element in producing a defensible uncertainty analysis study. Unfortu-nately, a systematic approach to distribution assignment
