glucopy.Gframe.qscore#

Gframe.qscore(slack: int = 0)[source]#

Calculates the Q-Score.

\[Q{-}score = 8 + \frac{\bar X -7.8}{1.7} + \frac{Range - 7.5}{2.9} + \frac{t_{G<3.9} - 0.6}{2.9} + \frac{t_{G>8.9} - 6.2}{5.7} + \frac{MODD - 1.8}{0.9}\]

\(\bar X\) is the sample mean (glucopy.Gframe.mean())
\(Range\) is the mean of the differences between the maximum and minimum glucose for each day.
\(t_{G<3.9}\) is the mean time [h] spent under 3.9 mmol/L in each day.
\(t_{G>8.9}\) is the mean time [h] spent over 8.9 mmol/L in each day.
\(MODD\) is the Mean of Daily Differences (glucopy.Gframe.modd()).

Parameters:: slack (int, default 0) – Maximum number of minutes that the given time can differ from the actual time in the data in the calculation of glucopy.Gframe.modd().
Returns:: qscore – Q-Score.
Return type:: float
