Andy's Survey Methodology Blog: Optimizing dual-frame RDD sample designs
http://www.andypeytchev.blogspot.com/2010/01/optimizing-dual-frame-rdd-sample.html
Andy's Survey Methodology Blog. Sunday, January 31, 2010. Optimizing dual-frame RDD sample designs. Mike Brick presented an interesting short course through ASA/SRMS last year, presenting much-needed work on optimum allocation of sample. S from landline and cell phone frames. In his examples, made-up numbers for cost per interview were used. Unfortunately, it is the cost estimates themselves. 1 A dual frame study should not use a landline sample from. I am a Research Assistant Professor at the Institute ...
Andy's Survey Methodology Blog: Nonresponse and Measurement Error

Andy's Survey Methodology Blog. Thursday, March 25, 2010. Nonresponse and Measurement Error. Survey researchers aim to minimize the effect of multiple sources of survey error, but they may not be independent; in fact, they may have common causes.

Andy's Survey Methodology Blog: The Role of the Survey Statistician: Beyond Sampling Error
http://www.andypeytchev.blogspot.com/2010/01/role-of-survey-statistician-beyond.html
Andy's Survey Methodology Blog. Friday, January 22, 2010. The Role of the Survey Statistician: Beyond Sampling Error. Not surprisingly, the sampling texts devote the majority of the content to sampling error. There are tradeoffs with other sources of error, however. Nonresponse, for example, is quite directly related to sampling; one could start with a much larger sample size and achieve more completed interviews at the expense of potential nonresponse error.

Andy's Survey Methodology Blog: Consequences of Survey Nonresponse

Andy's Survey Methodology Blog. Thursday, November 29, 2012. Consequences of Survey Nonresponse. I was asked to write a paper on the consequences of unit nonresponse in surveys ( http:/ ann.sagepub.com/content/645/1/88. I did a simple analysis for this paper that I found particularly intriguing. While a meta-analysis by Groves and Peytcheva found lack of association between nonresponse rates and nonresponse bias across. View my complete profile. The Cost of a Call Attempt.

Survey Methods Musings: Is the "long survey" dead?
http://jameswagnersurv.blogspot.com/2015/05/is-long-survey-dead.html
Blogging about survey methods, responsive design, and all things survey related. Friday, May 29, 2015. Is the "long survey" dead? A colleague sent me a link to a blog. Arguing that the "long survey" is dead. The blog takes the point of view that anything over 20 minutes is long. There's also a link to another blog. In my world 20 minutes is still a short survey. But the point is still taken. There has been some research. Matrix sampling is another useful approach that is little used. It seems like yo...
Survey Methods Musings: May 2015

Blogging about survey methods, responsive design, and all things survey related. Friday, May 29, 2015. From average response rate to personalized protocol. Researchers have since looked at subgroup response rates. Also interesting, but assuming that these rates are a fixed characteristic leaves us helpless. Now, it seems that we have begun working with an assumprton that there is heterogenous response to treatments and that we should, therefore, tailor the protocol and manipulate response propensities.

Blogging about survey methods, responsive design, and all things survey related. Friday, February 13, 2015. Adaptive Designs and Incentives. I've been working on a paper about an incentive experiment that we did. It raised some interesting issues. And made me recall one of my favorite papers. Trussell and Lavrakas. There are all sorts of ethical and procedural issues with offering differential incentives that make it difficult to carry out in practice, but I still think this is a neat example. I had the ...

Survey Methods Musings: Selection Effects
http://jameswagnersurv.blogspot.com/2015/05/selection-effects.html
Blogging about survey methods, responsive design, and all things survey related. Friday, May 8, 2015. This seems to come up in a number of different ways frequently. We talk a lot about nonresponse and how it may be a selective process such that it produces biases. We might try to model this process in order to correct these biases. If not, what else do we need to know? Subscribe to: Post Comments (Atom). View my complete profile. From average response rate to personalized protoco.
Survey Methods Musings: May 2014
http://jameswagnersurv.blogspot.com/2014_05_01_archive.html
Blogging about survey methods, responsive design, and all things survey related. Friday, May 30, 2014. Last week, I mentioned an experiment that we ran with changing the order of tracking steps. I noted that the overall result was that the original, expert-chosen order worked better than the new, proposed order. Friday, May 23, 2014. Tracking: Does Sequence Matter? That varied the order of steps. Friday, May 16, 2014. More on Measurement Error. Makes this point. If I have the "right" structure for my...

Blogging about survey methods, responsive design, and all things survey related. Friday, July 25, 2014. Responsive Design and Uncertainty. To my mind, a key reason for responsive designs is uncertainty. This uncertainty can probably occur in at least two ways. First, at a survey. Level, I can be uncertain about what response rate a certain protocol can elicit. If I don't obtain the expected response rate after applying the initial protocol, then I can change the protocol and try a different one. I had to...
Survey Methods Musings: November 2014
http://jameswagnersurv.blogspot.com/2014_11_01_archive.html
Blogging about survey methods, responsive design, and all things survey related. Friday, November 21, 2014. I came across this interesting po. About building a Bayesian model with careful specification of priors. The problem is that they have "tiny" data. So the priors play an important role in the analysis. I liked this idea of "tiny" data. The rush to solve problems for "big data" has obscured the fact that are interesting problems for situations where you don't have much data. I would argue that turni...

Blogging about survey methods, responsive design, and all things survey related. Friday, April 24, 2015. Responsive Design and Surveys with Short Time Frames. Another interesting question that I had during the webinar that I recently gave concerned responsive design and surveys with short time frames. I have to say, I mostly work on surveys with relatively long time frames. The shortest data collection that I have worked on in the last few years is about one month. Friday, April 17, 2015. There are diffe...

I wrote a paper on a call scheduling algorithm. I assigned a preferred calling window to each case.

Andy's Survey Methodology Blog. Tuesday, July 23, 2013. Is this a cell phone, a landline, or both? The demise of landlines as a technology? Currently, Random Digit Dial (RDD) telephone surveys can field samples from the landline and from the cell phone frames (sets of exchanges assigned to either service). The interviewers could confirm with the respondent whether they have reached a landline or a cell phone, and assign them to the correct stratum for weighting and estimation. Links to this post.
