I have looked through the new "Complex Surveys" book and the documentation for the "survey" package and it appears to me that there are no functions in "survey" that help one to design a sampling scheme. For example, in the book section 2.8 discusses the design of stratified samples, but there is no mention of any functions in the "survey" package that

Hello, I think this is an easy one for the average Rails developer but I''m a bit stuck. I''m creating a simple voting app: any user can create a survey, with any number of questions, and other users can then vote by creating a ballot for that survey. Here''s the modeling: class Survey < ActiveRecord::Base has_many :questions has_many :eligibilities has_many

Hi all, I have data collected from a survey administered on a subset of the population. I also have the population proportions of variables such as gender, race and housing type. I would like to combine the weights from each separate cross tab (of gender, race and housing type) such that the weighted proportions of my survey data matches that of the population. I have tried the following:

An organization has asked me to comment on the validity of their recent all-employee survey. Survey responses, by geographic region, compared with the total number of employees in each region, were as follows: > ByRegion All.Employees Survey.Respondents Region_1 735 142 Region_2 500 83 Region_3 897 78

Dear R-Helpers, SAS Institute just mailed out the notice below regarding a survey of people who do data mining. To help keep the survey from becoming biased toward commercial software, I thought it would be good to post it here as well. Cheers, Bob Fourth Annual Data Miner Survey Rexer Analytics has asked statistical and data mining software vendors to forward this survey as a courtesy. (SAS is

Greetings to all of the Shorewall community! We''d like to find out a little more about the environments in which Shorewall runs, and to this end i''ve created a survey. It is mostly designed to allow Shorewall users to see how their environment compares with that of the average Shorewall user (if such a thing exists!), but the results may be used by the Shorewall team to assist

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 Anything higher, and I get an

Hi R users, I am trying to use the aggregate function with a survey design object and survey functions, but get the following error. I think I am incorrectly using the syntax somehow, and it may not be possible to access variables directly by name in a survey-design object. Am I right? How do I fix this problem? I have used aggregate with "mean" and "weighted.mean", and

Dear Kevin, In addition to the advice you've received, take a look at the survey package. It's not quite what you're asking for, but in fact it's probably more useful, in that it provides correct statistical inference for data collected in complex surveys. The package is described in an article, T. Lumley (2004), Analysis of complex survey samples, Journal of Statistical Software

Warning: I am as green as #00FF00 with rails :-) I have an rhtml view that shows a survey: /views/survey/show.rhtml. I have a Survey model, helper and controller. I''m using the acts_as_commentable plugin to collect comments, and trying to save user comments from users who have taken a survey (don''t ask -- it''s just a test). To save the comment, I need the id of the

What Samba features do you care about most? Do you have problems or ideas to tell the Samba Team? Which parts of the documentation are most important to you? The Samba Team invites all users to participate in the Samba Survey at https://www.surveygizmo.com/s3/2020369/Samba-User-Survey-2015 The survey takes only 5-10 minutes to complete and runs until the end of March. We don't of course

R-help, Sorry for this question (I guess it has been addressed before but I could not find it in the archives) but how can I see a function code when the following comes up: > svymean function (x, design, na.rm = FALSE, ...) { .svycheck(design) UseMethod("svymean", design) } <environment: namespace:survey> Thanks in advance

I'm trying to learn how to calibrate/postStratify/rake survey data in preparation for a large survey effort we're about to embark upon. As a working example, I have results from a small survey of ~650 respondents, ~90 response fields each. I'm trying to learn how to (properly?) apply the aforementioned functions. My data are from a bus on board survey. The expansion in the

Hi R users, I request members of the R community to consider filling a short survey regarding the use of R. The survey can be found at http://goo.gl/jw1ig Please accept my apologies for posting here for a non-technical reason. The data collected will be suitably analyzed and I'll post a link to the results in the coming weeks. Thank you all for your interest and for sharing your R usage

Dear colleagues, Is there a way to order list items by date? I have a series of surveys in a list where the name of each list item is the date the survey was taken but the list items are out of order. Each data frame has a variable in it with the survey date as well, if that helps. Yours, Simon Kiss #Sample Data mylist<-list('1991-01-01'=data.frame(a=rep(5,5),

I am designing a solution for a hotel booking call center with the following (mandatory) design: After the call from the customer with the booking agent is complete (and the Hotel PBX disconnects from the call), a second PBX takes over to conduct a survey of how the call went. Both PBX's are Asterisk based. So customer phone [C] connects to hotel PBX [H]. Once [H] disconnects, the

Hello: I am working with a stratified survey dataset with sampling weights and I want to use multiple imputation to help with missingness. 1. Is there a way to run an ordered logistic regression using both a multiply imputed dataset (i.e. from mice) and adjust for the survey characteristics using the weight variable? The Zelig package is able to do binary logistic regressions for survey
