similar to: Problem with svyvar in survey package

Hi R users, I'm using the survey package to calculate summary statistics for a large health survey (the Demographic and Health Survey for Honduras, 2006), and when I try to calculate the variances for several variables, I get negative numbers. I thought it may be my data, so I ran the example on the help page: data(api) ## one-stage cluster sample dclus1<-svydesign(id=~dnum, weights=~pw,

Hello, svyvar from the survey package computes variances (with standard errors) from survey design objects. Is there any way to compute standard deviations and their standard errors in a similar manner? Thanks a lot, Sebastian

We are trying to install Samba 4 on a RHEL4 update 4 machine and are facing problems. We have downloaded the samba4 tar ball from http://repo.or.cz/w/Samba.git/snapshot/master.tar.gz After untarring it we have done cd source4 ./autogen.sh ./configure But at this stage itself we are getting the following error: /root/Samba/source4/wscript: error: Traceback (most recent call last): File

Hi all I would like to perform a logistic regression analysis on some complex survey data with R, but am not sure if there are functions within R that will enable me to do so. Also, are there any extensions of the "cor" function that would enable me to incorporate survey weights when calculating correlation coefficients for bivariate data. Any help on this matter will be greatly

How do I get utf-8 support with PCRE? I am having problems building lucene index using Zend_Lucene.

Dear All I like to develop an application using .NET and R. The front end would be .NET and statistical analysis would be done in R in the back end. So I want to integrate .NET(VB) with R without using any interface (e.g., R (D)com) to control. Secondly, I like to use Rscript (by calling .R files) from VB .NET environment for the analysis. Finally, I want to display the R-outputs including

Hello Does anybody happen to know if it is possible to use the survey package to estimate a covariance matrix from a complex survey? I have design weights and clusters (no strata), and want to get a covariance matrix with preferably the effective sample size or else an estimate of the variance-covariance matrix of the covariance matrix ("asymptotic covariance matrix"). Is this

Dear list, I have a data file which includes, alongside various variables representing questionnaire scores, a variable for survey weights computed as the number of observations in the sample drawn from that group divided by the number of observations in the population in the group. I need to calculate a covariance matrix of the questionnaire scores for use in sem. How do I apply the weights?

Hi all- So sorry to bother you all with something pretty basic. I am trying to add the lines method output from svysmooth to a svyplot with style="grayhex". However, the line either appears in the wrong place or if I am running in R Studio it causes the system to crash. I know this is something to do with Lattice graphics, but for the life of me I can not figure out how. Dr. Lumley

I am having trouble understanding (i.e. getting) confidence intervals from the survey package. I am using R version 2.8.1 (2008-12-22) and survey package (3.11-2) on FC7 linux. To simplify my question I use an example from that package: R> data(api) R> dclus1<-svydesign(id=~dnum, weights=~pw, data=apiclus1, fpc=~fpc) R> (tst <- svyby(~api99, ~stype,

Hi, I am trying to write a function to compute many cross-tabulations with the -svytable- command. Here is a simplified example of the structure of my code (adapted from the -svytable- help file): data(api) func.example<-function(variable){ dclus1<-svydesign(id=~1, weights=~pw,data=apiclus1, fpc=~fpc) svytable(~ variable, dclus1) } When I call this function with:

How do I retrieve the replicates estimates from a crosstab done using svyby? Here is an example from the help page for svyby in the package: > data(api) > dclus1<-svydesign(id=~dnum, weights=~pw, data=apiclus1, fpc=~fpc) > rclus1<-as.svrepdesign(dclus1) > > a <- svyby(~api99, ~stype, rclus1, svymean, return.replicates=TRUE) > a$replicates NULL But, compare to > b

Hi, I am facing a serious problem with file_column plugin. Though it is absolutely fine while uploading images, and the way it uploads the image on the file system and stores the file name in a database table is awsome. But while I try to get the image by passing its ID, surprisingly it returns the full absolute path rather than the image name! I would like to give a littel more description about

Hello! I'd like to create an assets-based economic indicator using data from a national household survey. The economic indicator is to be the first principal component from a principal components analysis, which (given the source of the data) I believe should take in consideration the sampling weights of the observations. After running the PCA with svyprcomp(), from the survey package, I
