Asymmetric Loss Functions and Sample Size Determination: A Bayesian Approach

open access: diamondAustrian Journal of Statistics, 2016
In designing monitoring systems for public health tasks it can be important to give different weights to the cases of under- and overestimation of a binomial parameter. We show how asymmetric loss functions can be used for this aim.
