Estimation of Bedtimes of Reddit Users: Integrated Analysis of Time Stamps and Surveys
The model is then applied to the application set, the remaining 50,000 users for whom time zone data but not bedtime data are available.

A Reddit ad was placed asking adult volunteers to complete a Qualtrics survey (Qualtrics International Inc) regarding their Reddit username, typical bedtime, range in bedtime, country, and state of residence.
