calcExpandedUncertainty method

Quantity calcExpandedUncertainty(
  1. double k
)

Returns the expanded uncertainty for coverage factor, k, in this Quantity's value as a typed Quantity object.

  • The expanded uncertainty is defined as a multiple of the standard uncertainty and may be used when the 68.27% confidence represented by the standard uncertainty (k=1) is not adequate.
  • Confidence values (i.e., the percentage of the distribution encompassed) for other values of the coverage factor 'k' include:
  1. 90% for k=1.645,
  2. 95.45% for k=2,
  3. 99% for k=2.576 and
  4. 99.73% for k=3.

Implementation

Quantity calcExpandedUncertainty(double k) =>
    dimensions.toQuantity(valueSI.abs() * _ur * k);
