Polling

This section is all about our own polling. We collect data from either online or mobile-based panels and then model and post-stratify the data with bleeding edge technology. Example of work include the PredictWise/Pollfish (with Wisconsin and Pennsylvania going to Trump) and MSN (with Wisconsin and Michigan going to Trump) 2016 election polling. Our methodology also showed Trump by 1 percentage point in Florida, where everyone else had Clinton from 1 to 4 percentage points.

Technical Details of PredictWise/Pollfish Poll (Click here for more detail!):
Pollfish runs in-application polling on third party mobile applications. We are reporting the modeled and post-stratified results. First, we run hierarchical logit regressions of the answers 1-7 on age, gender, geography, education, race, and party identification. This is run in Stan on R. Second, we estimate the population of likely voters using TargetSmart‘s voter file. We determine the percentage of the voters that are in any demographic cell (i.e., combination of demographics). Third, we post-stratify the results of the model onto the target populations of likely voters in the 2016 presidential election. This is experimental work, but we want to highlight three things:

Cheap: the retail cost of running each survey is $1,000 versus $20,000 retail for a comparable sized RDD telephone poll.

Fast: while we are trying to be consistent with the questions, we can add questions and have results in 1 or 2 hours. Further, the lower cost allows us to have high time granularity, which is prohibitively expensive with RDD data collection.

Accurate: our research shows that this method is accurate. But, we are also going to emphasize shifts in sentiment as much as levels of sentiment, where shifts in sentiment reflect the within survey design changes. As long we are surveying from a similar sample frame each week, the shifts are real within that sample frame, regardless of any concerns over the exact level of the sentiment.

There are two really topical papers to reference for this work. First, David and Sharad (along with Adam Obeng) have a paper called Non-Representative Surveys: Fast, Cheap, and Mostly Accurate which talks about the spectrum of data collection. Second, David and Sharad (along with Wei Wang and Andrew Gelman) have a paper called Forecasting elections with non-representative polls which talks about the analytics of modelling and post-stratifying in more depth.
