open access: yesRenaissance Studies, EarlyView.
Abstract This contribution explores for the first time a 22‐line poem in a British Library manuscript, ‘To a young lady that kept a flea chay'nd in a box’, which can be convincingly ascribed to Edmund Waller. Its most famous relative is Donne's ‘The Flea’, but its ancestry differs.

Self-Selection and Subjective Well-Being: Copula Models with an Application to Public and Private Sector Work [PDF]

open access: yes
We discuss a new approach to specifying and estimating ordered probit models with endogenous switching, or with binary endogenous regressor, based on copula functions. These models provide a framework of analysis for self-selection in economic well-being

Structured Expert Elicitation of Dependence Between River Tributaries Using Nonparametric Bayesian Networks

open access: yesRisk Analysis, EarlyView.
ABSTRACT In absence of sufficient data, structured expert judgment is a suitable method to estimate uncertain quantities. While such methods are well established for individual variables, eliciting their dependence in a structured manner is a less explored field of research.

Copulas and Dependence models in Credit Risk: Diffusions versus Jumps [PDF]

open access: yes
The most common approach for default dependence modelling is at present copula functions. Within this framework, the paper examines factor copulas, which are the industry standard, together with their latest development, namely the incorporation of ...

Distorted distributions and ROC curves

open access: yesScandinavian Journal of Statistics, EarlyView.
Abstract We consider new distortion functions based on the receiver operating characteristic (ROC) and ordinal dominance (OD) curves. Various stochastic orders and aging properties are characterized by using the interpretation of ROC and OD distortions as cumulative distribution functions of suitable relative random variables.

Bayesian inference for bivariate ranks

open access: yes, 2018
A recommender system based on ranks is proposed, where an expert's ranking of a set of objects and a user's ranking of a subset of those objects are combined to make a prediction of the user's ranking of all objects.
