WebThis paper presents a Bayesian analysis of shape, scale, and mean of the two-parameter gamma distribution. Attention is given to conjugate and “non-informative” priors, to sim- plifications of the numerical analysis of posterior distributions, and to comparison of Bayesian and classical inferences. KEY WORDS WebJul 6, 2024 · The gamma analysis has been used throughout IMRT dose verification. The commonly recommended gamma analysis standards are 3.0 mm, 3.0% [ 14, 15 ], but studies have shown that, depending on the technology and the disease, we should adopt stricter standards or other supplement analysis to analyze errors [ 26, 27 ].
