Using final sample weight in survey package
hi, probably not.. if your survey dataset has a complex design (like
clusters/strata), you need to include them in the `svydesign` call.
coercing an incorrect survey design into a replicate-weighted design will
not fix the problem of failing to account for the sampling strategy

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:

Retrieve regression summary results after rq
Hi all,
I am using quantile regression with svy design. I want to retrieve
summary regression statistics (std error, p-value), since I don't have
any in my output:

Survey package
Good afternoon!
I'm trying to use the Survey package for a stratified sample which has 4 criteria on which the stratification is based. I would like to get the corrected weights and for every element i get a weight of 1
E.g: tipping
design <- svydesign (id=~1, strata= ~regiune + size_loc + age_rec_hhh + size_hh, data= tabel)
and then weights(design)

Survey-weighted ordered logistic regression
Hi,
I am trying to fit a model with an ordered response variable (3 levels) and
13 predictor variables. The sample has complex survey design and I've used
'svydesign' command from the survey package to specify the sampling design.
After reading the manual of 'svyglm' command, I've found that you can fit a
logistic regression (binary response variable) by specifying the

Quantile regression (rq) and complex samples
I am new to R and am interested in using the program to fit quantile
regression models to data collected from a multi-stage probability
sample of the US population. The quantile regression package, rq, can
accommodate person weights. However, it is not clear to me that
boot.rq is appropriate for use with multi-stage samples (i.e., is
capable of sampling primary sampling units instead of survey

Comparison of means in survey package
Dear list colleagues,
I'm trying to come up with a test question for undergraduates to illustrate comparison of means from a complex survey design. The data for the example looks roughly like this:

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"

hardware / bandwidth requirements
Hi there!!
Any body can drop me some information about the hardware and bandwidth
requirements to setup an icecast server to stream real time video
using OGG/Theora? I'll setup an production server, and need to
calculate an estimate number of maximum clients connections to the
server.
thanks in advance,

Complex Surveys...Specifying Design
I need some guidance from someone who is familiar/has some experience with
the survey package.
The data that I am using is from the Medical Expenditure Panel Survey
(www.meps.ahrq.gov <http://www.meps.ahrq.gov/> ). The STRATA and PSU
variables are varstr01 and varpsu01 respectively. When I try to specify
them with the svydesign function I get an error message. An excerpt of my

calling svydesign function that uses model.frame
I need help on calling the svydesign function in the survey package
(although this error appears not to be specific to svydesign). I am
passing parameters incorrectly but am not sure how to correct the
problem.
## Call the main function PS.sim (one of mine). The dots are
parameters I omitted to simplify the question.
## y.col, str.col, clus.id, and PS.col are names of columns in the
object pop.

Survey and Stratification
Dear WizaRds,
Working through sampling theory, I tried to comprehend the concept of
stratification and apply it with Survey to a small example. My question
is more of theoretic nature, so I apologize if this does not fully fit
this board's intention, but I have come to a complete stop in my efforts
and need an expert to help me along. Please help:

Inserting weights in ltm package
Afternoon R help,
I want to run Rasch/IRT analyses using the ltm package, however, I am
using large scale survey data which requires weighting for accurate
results. I attempted to create a weighted object to insert into the
formulae of the ltm packages, however, the survey data only includes
30 replicate weights and a sampling weight. The svrepdesign requires
