Methods for the measurement of epidemic velocity from time-series data.
Two approaches to the measurement of epidemic velocity are presented. The first uses the moments of the frequency distribution of reported cases of a disease against time. The second is based upon an analysis of the growth parameter of a logistic model. The methods are illustrated by applications to some hypothetical and actual epidemic waves.
