Computed weighted variance
Description
This functions works quite equally as the wtd.var function
from the Hmisc package.
Usage
wtdVar(x , weights , na.rm = FALSE)
Arguments
x
numeric vector
weights
a numeric vector of non-negative weights
na.rm
set to FALSE to suppress checking for NAs. If TRUE, NAs are removed
from x as well as from weights prior to variance estimation.
Value
a scalar
Author(s)
Benjamin Becker
Examples
x <- c(50, 1, 25)
w <- c(1, 4, 1)
wtdVar(x, w)
