Protecting bottlenose dolphins from coastal construction
Professor Ann Weaver of Good-Natured Statistics Consulting, USA, has studied dolphins living free at sea for 20 years. Her numerous scientific discoveries about dolphin behaviour yield ample evidence of intelligence and of sophisticated social behaviour at sea. Drawing from many years of intensive studies in primates, she undertook an impressive 18-year ethological study of the social behaviour and impact of […]

Regression models using parametric pseudo-observations
The statistical analysis of survival data is the focus of research being carried out by Martin Nygård Johansen, a biostatistician at Aalborg University Hospital, Denmark, and his colleagues. Some patients’ actual survival times are not observed during a clinical study and are said to be censored. This research offers a new way to transform such time-to-event data into a dataset without censoring. […]
