A New Generated Family of Distributions: Statistical Properties and Applications with Real-Life Data

Computational and Mathematical Methods, 2023
Several standard distributions can be used to model lifetime data. Nevertheless, a number of these datasets from diverse fields such as engineering, finance, the environment, biological sciences, and others may not fit the standard distributions.

Estimation of the Tail Index of Pareto-Type Distributions Using Regularisation

Journal of Mathematics, 2022
In this paper, we introduce reduced-bias estimators for the estimation of the tail index of Pareto-type distributions. This is achieved through the use of a regularised weighted least squares with an exponential regression model for log-spacings of top ...

Trajectories of Physical Function in Canadian Children With Juvenile Idiopathic Arthritis

Arthritis Care &Research, EarlyView.
Objective We describe trajectories of physical function in children newly diagnosed with juvenile idiopathic arthritis (JIA) and identify trajectories with persisting functional impairments and associated baseline characteristics. Methods We included patients enrolled in the Canadian Alliance of Pediatric Rheumatology Investigators (CAPRI) Registry ...

Short‐Term Response to Biologic Therapy in Psoriatic Arthritis Is Not Influenced by Disease Duration at Initiation of Therapy

Arthritis Care &Research, EarlyView.
Objective We aimed to determine whether the short‐term response to biologics in biologic‐naive psoriatic arthritis (PsA) is better in patients initiating biologic treatment early in the disease course. Methods Patients with PsA who started on biologic therapy from the year 2000 to 2025 were included for analysis.
