Constrained least squares estimation lies at the heart of many applications in fields as diverse as statistics, psychometrics, signal processing, or even machine learning. Nonnegativity requirements on the model variables are amongst the simplest constraints that arise naturally, and the corresponding least-squares problem is called Nonnegative Least Squares or NNLS. In this paper we present a ...

We propose that physiological and performance tests used in sport science research and professional practice should be developed following a rigorous validation process, as is done in other scientific fields, such as clinimetrics, an area of research that focuses on the quality of clinical measurement and uses methods derived from psychometrics. In this commentary, we briefly review some of the...

Although medical education is a broad field of research and practice, it has come to be dominated by issues of assessment. Reasons for this emphasis range from the focus on accountability for educational outcomes to the established relationship between assessment and student motivation.
