title: Variance decomposition of tempo drift in isochronous rhythmic tapping.
abstract: The statistical techniques developed herein show strong promise as a nonparametric extension of the classical Wing-Kristofferson decomposition of variance in isochronous tapping to include tempo drift. It is now important to establish the relative role of the three sources of variance in discriminating among unselected individuals as well as selected populations differentiated by such factors as age, gender, and motor control impairment. We are currently making the estimation techniques available through the web, so that they can be applied to extant and new data. We can be contacted by e-mail for further information.
