Bayesian network for inferring group priors
Inferring the Latent Incidence of Inefficiency from DEA Estimates and Bayesian Priors
... In this paper we treat the true incidence 4 of inefficiency in a population of DMUs as a latent variable and the sample DEA estimates as a collection of sample observations that provide useful but noisy information ...

Bayesian nonparametric system reliability using sets of priors
