What we are reading: Comparative survey data, random effects and some best practice tips

Working with repeated comparative survey data – almost a howto There is now a bonanza of studies that rely on surveys which are replicated across countries and time, often with fairly short intervals, with the ESS arguably one of the most prominent examples (but also see the “barometer” studies in various regions). Multi-level analysis is…

Surveybias 1.4 is out

Surveybias 1.4 is out 1

Just how badly biased is your pre-election survey? Once the election results are in, our scalar measures B and B_w provide convenient, single number summaries. Our surveybias add-on for Stata will calculate these and other measures from either raw data or from published margins. Its latest iteration (version 1.4) has just appeared on SSC. Surveybias…

New (Free!) Software for Assessing Survey Bias

Worried about survey bias? We have updated our add-on (or ado) surveybias, which calculates our multinomial generalisation of the old Martin, Traugott, and Kennedy (2005) measure for survey bias. If you have any dichotomous or multinomial variable in your survey whose true distribution is known (e.g. from the census, electoral counts, or other official data),…

How to Get a 100 per cent Response Rate

When I drove home from work a couple of days ago, I noticed a policeman flagging down precisely every tenth car in the other lane and directing the drivers towards a lay-by. He was in uniform, wearing hi-vis gear and his government-issued Walther, so non-compliance was clearly not an issue. The scene was completed by a large billboard, stating that this was no ordinary vehicle spotcheck but rather a road use survey. I badly want these guys on our team.


Analysing Bias in French Pre-Election Surveys with surveybias for Stata (example 1/3)

In a recent publication (Arzheimer & Evans 2014), we propose a new multinomial measure B for bias in opinion surveys. We also supply a suite of ado files for Stata, surveybias, which plugs into Stata’s framework for estimation programs and provides estimates for this and other measures along with their standard errors. This is the first instalment in a mini series of posts that show how our commands can be used with real-world data. Here, we analyse the quality of a single French pre-election poll.
