ratioWithUncertainty
ratioWithUncertainty(
value,relativeUncertaintyValue,baseline,relativeUncertaintyBaseline):RatioWithUncertainty
Defined in: uncertainty.ts:26
Ratio of two independently-measured quantities, with the uncertainty propagated from each operand’s own relative uncertainty.
Reporting a ratio without an error term invites reading noise as signal: the relative uncertainty of a quotient of two independent quantities is the quadrature sum (root sum of squares) of their own relative uncertainties.
Parameters
Section titled “Parameters”number
Numerator.
relativeUncertaintyValue
Section titled “relativeUncertaintyValue”number
value’s dispersion as a fraction of value
(e.g. a relative standard deviation).
baseline
Section titled “baseline”number
Denominator.
relativeUncertaintyBaseline
Section titled “relativeUncertaintyBaseline”number
baseline’s dispersion as a fraction of
baseline.
Returns
Section titled “Returns”NaN for both fields when baseline is 0.
