glucopy.Gframe.gvp#

Gframe.gvp()[source]#

Calculates the Glucose Variability Percentage (GVP), with time in minutes.

\[GVP = \left( \frac{L}{T_0} - 1\right) * 100\]

\(L = \sum_{i=1}^N \sqrt{\Delta X_i^2 + \Delta T_i^2}\)
\(T_0 = \sum_{i=1}^N \Delta T_i\)
\(N\) is the number of glucose readings.
\(\Delta X_i\) is the difference between glucose values at time i and i-1.
\(\Delta T_i\) is the difference between times at time i and i-1.

Parameters:: None –
Returns:: gvp – Glucose Variability Percentage.
Return type:: float
