Intermediate clinical endpoints as surrogates for overall survival after salvage prostatectomy

open access: yesBJU 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 ...

Comparing Foster and Non‐Foster Adolescents: A Pilot Study on Relationships and Psychological Difficulties

open access: yesChild &Family Social Work, EarlyView.
ABSTRACT Adolescents experience substantial changes in their close relationships, which are linked to psychological adjustment. Research on relationships among adolescents in foster care is limited, especially in Germany. This pilot study (N = 30; 15 in foster families, 15 in biological families) explored how relationship qualities—measured by the ...

Fast Estimation of Kendall's Tau and Conditional Kendall's Tau Matrices under Structural Assumptions

open access: yes, 2022
Kendall’s tau and conditional Kendall’s tau matrices are multivariate (conditional) dependence measures between the components of a random vector. For large dimensions, available estimators are computationally expensive and can be improved by averaging ...

Changes in the transformative potential of action proposals in Finnish Red Lists from 1986 to 2019

open access: yesConservation Biology, EarlyView.
Abstract Red lists provide critical knowledge regarding biodiversity decline, especially in Finland, where broad assessments have been made regularly since the 1980s. They deliver information on the threat status of species and ecosystems, propose actions to guide conservation policy, and have the potential to spur transformative change.

Discussion of credit risks added Nov. 28, 2002 KENDALL’S TAU FOR ELLIPTICAL DISTRIBUTIONS ∗

open access: yes, 2002
. By using well known properties of elliptical distributions we show that the relation between Kendall’s tau and the linear correlation coefficient for bivariate normal distributions holds more generally (subject to only slight modifications) for the ...

Limited elephant impacts on baobabs despite increasing elephant densities in a newly established protected area

open access: yesConservation Science and Practice, EarlyView.
Researchers combined aerial and ground surveys to map baobab distribution and assess elephant herbivory impacts on baobabs across Karingani Game Reserve, Mozambique. Researchers found that aerial surveys were an effective tool for mapping baobabs and that baobabs were more likely to occur closer to permanent water, at lower elevations, and in areas ...

Non-parametric dependence modeling for financial markets using conditional Kendall's tau

open access: yes, 2022
In this thesis, we have examined conditional dependence in a financial context using conditional Kendall’s tau (CKT). The conditional Kendall’s tau is a measure of concordance between two random variables given some covariates.
