Dear R users,

Version 1.1 of the EVER package is on CRAN.

EVER (the acronym stands for Estimation of Variance by Efficient Replication) is mainly intended for calculating estimates and standard errors from complex surveys.
Variance estimation is based on the extended Delete-A-group Jackknife technique proposed by Dr. Phillip S. Kott.

The advantage of the DAGJK method over the traditional jackknife is that, unlike the latter, it remains computationally manageable even when dealing
with "complex and big" surveys (tens of thousands of PSUs arranged in a large number of strata with widely varying sizes).

Thanks,

Diego Zardetto
