Psychological distress and mother-child relationship: influence of life context on a population sample (BRISA) through the use of directed acyclic graphs (DAG) [PDF]
Brazilian Journal of Medical and Biological ResearchThis study aimed to investigate the association between maternal psychological distress and impairment in mother-child relationship in a sample from a Northeast capital city in Brazil with a low Human Development Index, using directed acyclic graphs (DAG)

Search and sweep numbers of finite directed acyclic graphs [PDF]
, 1993 The search number of a graph is the least number of searchers needed to find any (possibly infinitely fast) intruder hiding in the vertices or edges of the graph.

Arthritis &Rheumatology, EarlyView.Objective The purpose of this study was to estimate the prevalence of difficult‐to‐manage (D2M) and treatment‐refractory (TR) axial spondyloarthritis (axSpA) and to identify factors associated with D2M and TR disease in a longitudinal cohort. Methods We performed a cross‐sectional analysis on data from the Schroeder Arthritis Institute Spondylitis ...

Acyclic partitioning of large directed acyclic graphs [PDF]
, 2018 We investigate the problem of partitioning the vertices of a directed acyclic graph into a given number of parts. The objective function is to minimize the number or the total weight of the edges having end points in different parts, which is also ...

Minimal sufficient causation and directed acyclic graphs
, 2019 Notions of minimal sufficient causation are incorporated within the directed acyclic graph causal framework. Doing so allows for the graphical representation of sufficient causes and minimal sufficient causes on causal directed acyclic graphs while ...

Arthritis &Rheumatology, EarlyView.Objective The Assessment of SpondyloArthritis international Society recently defined early axial spondyloarthritis (axSpA) as a duration of two years or less of axial symptoms. Previous studies have shown no significant difference in short‐term outcomes between patients with early and established axSpA treated with biologic/targeted synthetic disease ...

Homophily‐adjusted social influence estimation
Canadian Journal of Statistics, EarlyView.Abstract Homophily and social influence are two key concepts of social network analysis. Distinguishing between these phenomena is difficult, and approaches to disambiguate the two have been primarily limited to longitudinal data analyses. In this study, we provide sufficient conditions for valid estimation of social influence through cross‐sectional ...
