The 2019 data challenge expo of the American Statistical Association.

The text introduces the Data Challenge Expo 2019, an annual event sponsored by the American Statistical Association. The challenge involves analyzing a data set from the New York City Housing and Vacancy Survey. Participants were asked to explore various research questions related to housing conditions, rent control, gentrification, immigrant residency, and the costs and benefits of renting versus owning in New York City. The winners of the challenge were announced at the Joint Statistical Meetings in 2019, and their analyses are described in this special issue of Computational Statistics. Supplementary materials, including data sets and code, are available for reproducibility purposes. [Extracted from the article]
