Modeling traumatic brain injury lifetime data: Improved estimators for the Generalized Gamma distribution under small samples
Fig 3
Comparison of the different estimation methods.
Bias and MSE of the estimates of ϕ = 0.4, μ = 1.5 and α = 4, for N = 20, 000 simulated samples of size n, and using the following methods: 1-ML, 2-PML, 3-MPS, 4-AD, 5-RAD. The horizontal lines in these figures correspond to bias and MSE equal to zero. See text for explanations, definitions and notation.
