Version 3.26 of the survey package is percolating through CRAN. Since
the last announcement on this list, of version 3.20, about 18 months
ago, the main changes are
-- an option to calculate replicate-weight variances from sums of
squares around the point estimate rather than from the variance of the
replicates ("MSE" style)
-- Preston's multistage rescaled bootstrap, which is valid for any
number of stages of sampling and arbitrary sampling fractions
-- wider use of, and better asymptotic approximations for the
Rao-Scott likelihood ratio tests
-- trimming of weights
A lot of minor bugs and infelicities have also been fixed. More
details are in the NEWS file.
