Intermediate clinical endpoints as surrogates for overall survival after salvage prostatectomy
BJU International, EarlyView.Objectives To evaluate biochemical recurrence‐free survival (BRFS) and metastasis‐free survival (MFS) as potential intermediate clinical endpoints (ICEs) for overall survival (OS) in patients undergoing salvage radical prostatectomy (sRP). Patients and Methods Evaluable patients were selected from a retrospective dataset, resulting in a cohort of 879 ...

LLM‐based prior elicitation for Bayesian graphical modeling
British Journal of Mathematical and Statistical Psychology, EarlyView.ABSTRACT In the Bayesian graphical modeling framework, priors on network structure encode theoretical assumptions and uncertainty about the topology of psychological constructs under study. For instance, the Bernoulli prior specifies the probability of each pairwise interaction, the Beta–Bernoulli prior governs expected network density, and the ...

Testing the bivariate distribution of daily equity returns using copulas. An application to the Spanish stock market [PDF]
In this paper we deal with the identification of dependencies between time series of equity returns. Marginal distribution functions are assumed to be known, and a bivariate chi-square test of fit is applied in a fully parametric copula approach. Several

Non-Parametric Inference for Bivariate Extreme-Value Copulas [PDF]
Extreme-value copulas arise as the possible limits of copulas of componentwise maxima of independent, identically distributed samples.The use of bivariate extreme-value copulas is greatly facilitated by their representation in terms of Pickands ...

Learning gains from work placements: Innovative behavior and the role of emotional competencies
European Management Review, EarlyView.Abstract The importance of innovative behavior (IB) has been well documented, and the engagement of employees in IB has become a tacit norm in many organizations. It has also been understood that IB is emotionally charged. However, little research has concentrated on whether higher education (HE) providers can foster IB in university students, and ...
