RSPEEDINDEX: Stata module to compute a response speed index and perform outlier identification

Joss Roßmann

Statistical Software Components from Boston College Department of Economics

Abstract: The rspeedindex command computes a response speed index on the basis of question block, page or item level response times in survey data. The index values can be interpreted as a measure of the mean response speed of survey respondents. In addition, the rspeedindex command generates a variable to flag response speed outliers. Thereby, it can be specified whether response speed outliers in the lower (i.e., fast respondents), the upper (i.e., slow respondents), or both directions are detected. Three different methods to generate cutoff values for the identification of response speed outliers are available. These include the use of percentiles, standard deviations from the mean of the distribution, and absolute values of the response speed index.
