Tamanho amostral para estimar a concentração de organismos em água de lastro: uma abordagem bayesiana

Optimal sample size for the Birnbaum-Saunders distribution under a decision-theoretic approach

“…In each value of n in the grid, we estimate the Bayes risk ten times. Costa (2017) propose to fit the following curve to the grid of values of n and the respective…”

“…The Bayes rule d * n corresponds to taking a and b as the quantiles of probabilities ρ/2 and 1 − ρ/2 of the posterior distribution of θ. For more details see Rice et al (2008) or Costa (2017). If we consider this loss function applied to the Bayes rule, we have…”

“…. For more details see Rice et al (2008), Parmigiani & Inoue (2009) or Costa (2017). For this loss function, we have…”

“…We consider four different loss functions for point and interval inference, two for each type of inference. Using the same approach but for other models there is a considerable literature, see for example Etzioni & Kadane (1993), Sahu & Smith (2006), Parmigiani & Inoue (2009), Islam & Pettit (2012, 2014), De Santis & Gubbiotti (2016, Costa (2017) and references therein.…”
