In this study, per-person municipal expenditures were modeled as a function of six demographic and income-related variables, first using a robust linear regression model (LM), and second using a generalized additive model (GAM). A comparison of the two models revealed that the GAM provided more accurate predictions, and therefore we recommend for the client to use the GAM as the basis for predi...

Dan Zhang Leads School of Business, University of Colorado at Boulder, Boulder, CO 80309, USA [email protected] Inventory-based dynamic pricing has become a common operations strategy in practice and has received considerable attention from the research community. From an implementation perspective, it is desirable to design a simple policy like a base stock list price (BSLP) policy. The e...

In the paper we propose nonparametric approaches for elearning data. In particular we want to supply a measure of the relative exercises importance, to estimate the acquired Knowledge for each student and finally to personalize the e-learning platform. The methodology employed is based on a comparison between nonparametric statistics for kernel density classification and parametric models such ...

It is well known that using individual covariate information (such as body weight or gender) to model heterogeneity in capture–recapture (CR) experiments can greatly enhance inferences on the size of a closed population. Since individual covariates are only observable for captured individuals, complex conditional likelihood methods are usually required and these do not constitute a standard gen...
