medvol

Calculates and returns the standard deviation of a vector

This is an R package implementing the epidemic volatility index (EVI), as
discussed by Kostoulas et. al. (2021) and variations by Pateras et. al. (2023). EVI is a new, conceptually simple, early warning tool for oncoming epidemic waves.
EVI is based on the volatility of newly reported cases per unit of time,
ideally per day, and issues an early warning when the volatility change rate exceeds a threshold.
