In MESS: Miscellaneous Esoteric Statistical Scripts
usd R Documentation
Unbiased standard deviation
Description
This function computes the unbiased standard deviation of the values in x. If na.rm is TRUE then missing values are removed before computation proceeds.
Usage
usd(x, na.rm = FALSE)
Arguments
x
a numeric vector or an R object but not a factor coercible to numeric by as.double(x)
na.rm
logical. Should missing values be removed?
Details
Like var this uses denominator n - 1.
The standard deviation of a length-one or zero-length vector is NA.
Value
A scalar
Examples
sd(1:5)
usd(1:5)
