specifying as.svrepdesign with odd number PSUs
Is there a way to create a BRR svrepdesign from a survey design when the number of PSUs is odd in one or more stratum? Creating a JKn svrepdesign with that condition works okay, but when I tried to create a svrepdesign with type="BRR" I get an error and this message:
"Can't split with odd numbers of PSUs in a stratum"
I get that message when I tell it to merge the

survey package
A new package `survey' for analysing complex survey samples is on CRAN.
It handles stratification, clustering, and unequal sampling probabilities
in descriptive statistics, glms, and general maximum likelihood fitting.
The package is still under development:
- it doesn't do the finite population correction to variances
- it needs some real life worked examples
Most importantly,

survey package (3.18)
Version 3.18 of the survey package is now percolating through CRAN.
Since the last announcement on this list, in February, the main additions are
- standard errors for survival curves (both Kaplan-Meier and Cox model)
- svyciprop() for confidence intervals on proportions, especially in small samples or near 0 or 1.
- predictive margins by direct standardization, with marginpred()

Memory Problems with CSV and Survey Objects
I'm working with a 350MB CSV file on a server that has 3GB of RAM, yet I'm
hitting a memory error when I try to store the data frame into a survey
design object, the R object that stores data for complex sample survey data.
When I launch R, I execute the following line from Windows:
"C:\Program Files\R\R-2.9.1\bin\Rgui.exe" --max-mem-size=2047M

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

Version 3.9 of the survey package is now on CRAN. Since the last
announcement (version 3.6-11, about a year ago) the main changes are
- Database-backed survey objects: the data can live in a SQLite (or other
DBI-compatible) database and be loaded as needed.
- Ordinal logistic regression
- Support for the 'mitools' package and multiply-imputed data

[Fwd: Re: mixed models for analyzing survey data with unequal selection probability]
Hi, All
Thanks to Robert Baskin, Thomas Lumley, and Spencer Graves for the
valuable helps. I have learned a lot from this discussion.
I put all discussions together without editing, so we can see how things
are evolved. Likely, I have a lot of articles to read. As in the
discussion, mixed modeling approach is a poosible but may be over-kill
in my posted data analyses. I will explore other

new version of survey package
Version 2.9 of survey is on CRAN. In addition to various minor
improvements and bug fixes there are two major changes
- full multistage finite-population sampling is supported (as in SUDAAN)
- the same analysis commands can be used for all design types (eg svymean
instead of svrepmean for replicate weight designs)
