svy / weighted regression
Dear list,
I am trying to set up a propensity-weighted regression using the
survey package. Most of my population is sampled with a sampling
probability of one (that is, I have the full population). However, for
a subset of the data I have only a 50% sample of the full population.
In previous work on the data, I analyzed these data using SAS and
STATA. In those packages I used a propensity weight

SVY: variance inflation factor VIF with complex survey
Hello,
Seeking a way to get the variance inflation factor VIF for a model of regression in complex survey, I have understood that without this package (SURVEY) RGui VIF obtained as follows:
fit <- lm(mpg~disp+hp+wt+drat, data=mtcars)
vif(fit)
But I want to know if survey, Vif is obtained so
vif( svyglm(api00~ell+meals+mobility, design=dstrat))
Thank you, happy day

Using calibrate for raking (survey package)
I'm studying the calibration function in the survey package in preparation
for raking some survey data. Results from the rake function below agree
with other sources. When I run calibrate, I get a warning message and the M
and F weights seem to be reversed. Even allowing for that, the deviation
between calibrated and raked weights is much more than I expected. I see
that in the calibrate

Direct Method Age-Adjustment to Complex Survey Data
Hi everyone, my apologies in advance if I'm overlooking something simple in
this question. I am trying to use R's survey package to make a direct
method age-adjustment to some complex survey data. I have played with
postStratify, calibrate, rake, and simply multiplying the base weights by
the correct proportions - nothing seems to hit the published numbers on the
nose.

SURVEY PREDICTED SEs: Problem
Hello R-list,
I'm attempting to migrate from Stata to R for my complex survey
work. It has been straight-forward so far except for the
following problem:
I have some code below, but first I'll describe the problem.
When I compute predicted logits from a logistic regression, the
standard errors of the predicted logits are way off (but the
predicted logits are fine). Furthermore, the

Risk differences with survey package
I'm trying to use the survey package to calculate a risk difference with
confidence interval for binge drinking between sexes. Variables are
X_RFBING2 (Yes, No) and SEX. Both are factors. I can get the group
prevalences easily enough with
result <- svyby(~X_RFBING2, ~SEX, la04.svy, svymean, na.rm = TRUE)
and then extract components from the svyby object with SE() and coef() to
do the

Simple frequencies using svy design
Hello,
excuse me if this is trivial. I have some survey data with the following
design
MyDesign<-(id=ident, weights=~fwgt, fcp=~nval1+nval2, data=hh_data1)
I would like to run simple frequency tables such as those provided by the
freq() function of rgrs to check the impact of the sampling design on my
Ns. Anyway I can do this? thanks, V

svy equivalent of pairwise.t.test
Dear all,
I am looking for an equivalent of the pairwise.t.test() function using a

weights using the pairwise.t.test itself? Thanks, V

V-Cramer in svy
Hello forum,
I want to find in survey how to test V-cramer and coefficient Goodman-Kruskal gamma, to test the collinearity between varibles to enter a model.
For the V-Cramer function is used with the package vcd assocstats but without considering the survey package.
I appreciate the cooperation.

Svy function doesn't work nested in user-defined function
Hi R-help,
I posted about this late yesterday but got no response. I may have put
TMI in the original request. Not to mention I couldn't cut and paste
yesterday because I was working R off a non-network computer while
asking for help on a network computer.
Essentially, I have this user-defined function:

reshape package does not recognize second id variable
I am trying to use the reshape package for the first time. I have two
waves of a survey, so the id variables include a subject
identification number and a variable denoting the wave of the survey.
I used the following arguments:

(svy)glm and weights question
Hi all,
I am running a set of logistic regressions, where we want to use some
weights, and I am not sure whether what I am doing is reasonable or
not.
The dependent variable is turnout in an election - i.e. survey
respondents were asked whether or not they voted. The percentage of
those who say they voted is much higher than the actual turnout,
probably due both to non-response bias and social
