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

The 'test.terms' argument in 'regTermTest' in package 'survey'
This is a question regarding the 'regTermTest' function in the 'survey' package. Imagine Z as a three level factor variable, and code ZB and ZC as the two corresponding dummy variables. X is a continuous variable. In a 'glm' of Y on Z and X, say, how do the two test specifications
test.terms = c("ZB:X","ZC:X") # and
test.terms = ~ ZB:X + ZC:X

R: Confidence Intervals for logistic regression
a closer look to the help on predict.glm will reveal that the function
accepts a 'type' argument.
In you case 'type = response' will give you the results in probabilities
(that it seems to be what you are looking for).
There also is an example on use of the 'type' argument at the end of the
page.

svydesign syntax
This message is for those familiar with the survey package. I need to fit a
weighted Cox model to accommodate the sampling weights as I have a
case-control study with controls sampled at random from a database in a
ratio 2:1 to cases (whom were all sampled). I want to make sure I am using
the right svydesign syntax to specify this sampling design. Can anyone
please check if the statement below is

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.

Dimensions on svychisq on svydesign
Dear Forum
I a running svychisq from the survey package and get errors with the number
of dimensions,
errors that I do not understand and do not know how to fix.
I ask you kindly to help me out.
The eror message follows with some information below. I hope there are
enough information to help me to fix the problem if not please let me know
what is needed

Struggeling with svydesign()
Dear all,
We are analysing some survey data and we are not sure if we are using
the correct syntax for our design.
The population of interest is a set of 4416 polygons with different
sizes ranging from 0.003 to 45.6 ha, 7460 ha in total. Each polygon has
a binary attribute (presence/absence) and we want to estimate the
probability of presence in the population.
We used sampling with replacement

Testing strata by covariate interactions in coxph
Dear list members,
I am working with a Cox ph model for the duration of unemployment. The event of
interest
in my analysis is getting employed. I have various background variables
explaining this
event: age, sex, education etc. I have multiple unemployment spells per person.
I use a model with person-specific frailty terms in order to take into account

Power Law Exponents
I am having difficulty with the calculation of the power law exponent
for set of nodes within a graph.
Specifically, I am interested in the distribution of in-degree and
out-degree among communities of web pages where the web pages are the
nodes of the graph and the hyperlinks the edges.
According to the literature, the distribution of incoming and outgoing
links obeys a power law distribution

Warning message: In eval(expr, envir, enclos) : non-integer #successes in a binomial glm!
Hi there
I'm trying to fit a logistic regression model to data that looks very similar to the data in the sample below. I don't understand why I'm getting this error; none of the data are proportional and the weights are numeric values. Should I be concerned about the warning about non-integer successes in my binomial glm? If I should be, how do I go about addressing it?

svyglm and sandwich estimator of variance
Hi,
I would like to estimate coefficients using poisson regression and then get
standard errors that are adjusted for heteroskedasticity, using a complex
sample survey data. Then I will calculate prevalence ratio and confidence
intervals.
Can sandwich estimator of variance be used when observations aren?t
independent? In my case, observations are independent across groups
(clusters), but

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

crosstable and regression for survey data (weighted)
I have survey data that I am working on. I need to make some multi-way tables
and regression analyses on the data. After attaching the data, this is the
code I use for tables for four variables (sweight is the weight variable):
> a <- xtabs(sweight~research.area + gender + a2n2 + age)
> tmp <- ftable(a)
Is this correct? I don't think I need to use the strata and cluster

Hello,
I'm trying to use the function svyglm in the library survey.
I create a data survey object:

Cómo aplicar weights a las observaciones en un GLM binomial
Gracias por la ayuda Jose Luis. pero o no te he entendido bien o mi duda es
tan sencilla que no me he explicado.
SI yo tampoco he entendido mal tu explicación, mi problema es cómo obtengo
ese "tus.pesos" para introducir, por ejemplo, en la función:
library(survey)
# objeto del diseño muestral
ddatos <- svydesign(id=~1, weights =~ tus.pesos, data = tus.datos)
