diabetic-utils / glucoseCoefficientOfVariation

Function: glucoseCoefficientOfVariation()

glucoseCoefficientOfVariation(readings): number

Defined in: variability.ts:48

Calculates the coefficient of variation (CV) for glucose values. CV = (SD / mean) × 100. Used to assess glycemic variability.

Parameters

readings

number[]

Array of glucose values (numbers)

Returns

number

Coefficient of variation as a percentage, or NaN if <2 values or mean is 0

Throws

If readings is not an array

See

ADA 2019: Glycemic Targets

Example

glucoseCoefficientOfVariation([100, 120, 140]) // 18.26
glucoseCoefficientOfVariation([100]) // NaN
glucoseCoefficientOfVariation([]) // NaN

Remarks

• If readings contains <2 values or mean is 0, returns NaN.
• Handles NaN/Infinity values by propagating them in the result.
