CONGA.fn: Function to calculate the continuous overlapping net glycemic action (CONGA)

Description

For each observation after the first n hours of observations, the difference between the current observation and the observation n hours previous was calculated. CONGA is defined as the standard deviation of the differences.

Usage

CONGA.fn(y, Interval = 5, n = 2)

Value

a value of CONGA

Arguments
