Title
Working with User Agent Strings in Stata: The parseuas Command
Subject
user agent string, web surveys, device detection, browser, paradata, Stata.
Description
With the rising popularity of web surveys and the increasing use of paradata by survey
methodologists, assessing information stored in user agent strings becomes inevitable.
These data contain meaningful information about the browser, operating system, and
device that a survey respondent uses. This article provides an overview of user agent
strings, their specific structure and history, how they can be obtained when conducting
a web survey, as well as what kind of information can be extracted from the strings.
Further, the user written command parseuas is introduced as an efficient means to gather
detailed information from user agent strings. The application of parseuas is illustrated
by an example that draws on a pooled data set consisting of 29 web surveys.
