Used in probabilistic sensitivity scenario analyses; standard error (SE) based on an assumption that mean costs vary by ±25%.

Gamma distributions were assigned in probabilistic sensitivity analysis, assuming SE to the mean cost of 25%. Two parameters of the gamma distribution (α, λ) are derived from the mean and SE. Formulas for these calculations are: α = (Mean²)/(SE²); λ= Mean/([Mean × SE]²).
