sd.u: Unbiased Standard Deviation
In dmarginean/aqua: Assay Qualification Tools
sd.u R Documentation
Unbiased Standard Deviation
Description
Unbiased Standard Deviation. Very helpful when sample size is small, especially less than 6,
which is very common in assay qualification or validation runs. Regular sample standard deviation
can be up to 20% biased when the sample size is 3, for example. This one isn't.
Usage
sd.u(x)
Arguments
x
A vector of (normally-distributed) numbers
Value
The corrected/unbiased standard deviation of the input vector, based on a chi-distributed correction factor (c4)
Examples
sd.u(rnorm(10, 0, 4))
