OBSOFINT: Stata module to display observations of interest

Abstract: obsofint is intended to help scan a large number of variables for unusual observations. These unusual observations are unusual in the sense that they either have a much smaller or a much larger value on a given variable than the bulk of the data. These observations of interest are identified using a criterium that is an adaptation of the commonly used Tukey bounds used in for example boxplots. In our experience these Tukey bounds flag too many values as extreme values if a variable is either skewed or has a spike (a value that is very common). The rule used in obsofint is meant to result in less false positives in case skewed or spiked variables.
