Excess Mass Estimates and Tests for Multimodality

TL;DR: In this article, a method for analyzing the modality of a distribution is proposed based on the excess mass functional, which measures excessive empirical mass in comparison with multiples of uniform distribution.
Journal ArticleDOI

Specificity of affective instability in patients with borderline personality disorder compared to posttraumatic stress disorder, bulimia nervosa, and healthy controls.

TL;DR: The results give raise to the discussion if affective instability is a transdiagnostic or a disorder-specific mechanism, and investigating psychopathological mechanisms in everyday life across disorders is a promising approach to enhance validity and specificity of mental health diagnoses.
Journal ArticleDOI

Ambulatory assessment of affective instability in borderline personality disorder: The effect of the sampling frequency.

TL;DR: In this article, the authors used 24-hour ambulatory monitoring to assess subjective ratings of distress in 50 borderline personality disorder (BPD) patients and in 50 healthy controls and found that the chosen time-based design with a time interval of 15 min between self-reports (1) reveals within subject variability in BPD-patients and (2) taps the process of interest.
Journal ArticleDOI

Report on the numerical reliability of data analysis systems

TL;DR: The results show considerable problems even in basic features of well-known systems, and the omissions and failures observed here give some suspicions of what happens in less well-understood problem areas of computational statistics.
