Description Usage Arguments Value See Also Examples

sdw calculates weighted standard deviations of a sample using the individual weights of all components.

1	sdw(xs, corr = cormid)

`xs`	object from class `wtsamp` containing the sample and weights for components' distributions.
`corr`	function used for correction of weights before sd caclucation. (no correction if codecorr=NULL).

a vector of components' standard deviations
