Principal components are a well established tool in dimension reduction. The extension to principal curves allows for general smooth curves which pass through the middle of a multidimensional data cloud. In this paper local principal curves are intro... Read More about Local Principal Curves.

Model free endurance markers based on the second derivative of blood lactate curves (2005)
Presentation / Conference Contribution
Newell, J., Einbeck, J., Madden, N., & McMillan, K. (2005, July). Model free endurance markers based on the second derivative of blood lactate curves. Presented at 20th International Workshop on Statistical Modelling., Sydney

Blood lactate assessment is used regularly by exercise physiologists as a predictor of endurance performance. Typically fingertip blood samples are collected at selected running speeds on a treadmill and a plot of lactate concentration against worklo...

Exploring Multivariate Data Structures with Local Principal Curves (2005)
Presentation / Conference Contribution
Einbeck, J., Tutz, G., & Evers, L. (2005, January). Exploring Multivariate Data Structures with Local Principal Curves. Presented at 28th Annual Conference of the German Classiciation Society., Magedeburg, Germany

A new approach to find the underlying structure of a multidimensional data cloud is proposed, which is based on a localized version of principal components analysis. More specifically, we calculate a series of local centers of mass and move through t... Read More about Exploring Multivariate Data Structures with Local Principal Curves.
