Neural Network Studies. 2. Variable Selection

Journal of Chemical Information and Computer Sciences, 1996
Quantitative structure-activity relationship (QSAR) studies usually require an estimation of the relevance of a very large set of initial variables. Determination of the most important variables allows theoretically a better generalization by all pattern recognition methods.

Variability of repeated nerve conduction studies

Electroencephalography and Clinical Neurophysiology/Evoked Potentials Section, 1991
We have determined the variability of repeated measurements of sensory nerve action potential (SNAP) and compound muscle action potential (CMAP) amplitude and motor and sensory conduction velocity (MCV and SCV) and examined the extent to which limb temperature is responsible for the variability. We made 10 serial measurements of SNAP, CMAP, MCV and SCV
