    Data envelopment analysis efficiency in the public sector using provider and customer opinion: An application to the Spanish health system

    Measuring the relative efficiency of a finite fixed set of service-producing units (hospitals, state services, libraries, banks,...) is an important purpose of Data Envelopment Analysis (DEA). We illustrate an...

    Isotonic boosting classification rules

    In many real classification problems a monotone relation between some predictors and the classes may be assumed when higher (or lower) values of those predictors are related to higher levels of the response. I...

    Data envelopment analysis in satisfaction survey research: sample size problem

    Data envelopment analysis (DEA) frequently uses stochastic input and/or output data. If these data are estimated from a sample in each decision-making unit, the DEA efficiency will be an estimation of the obta...

    Classification of Samples with Order-Restricted Discriminant Rules

    In recent years, mass spectrometry techniques have helped proteomics to become a powerful tool for the early diagnosis of cancer, as they help to discover protein profiles specific to each pathological state. ...

    Efficient Incorporation of Additional Information to Classification Rules

    We propose and discuss improved classification rules when a subset of the predictors is known to be ordered. We compare the performance of the new rules with other standard rules in a restricted normal setting...

    Bayes Discriminant Rules with Ordered Predictors

    We propose and discuss improved Bayes rules to discriminate between two populations using ordered predictors. To address the problem we propose an alternative formulation using a latent space that allows to in...
