xfrac provides a specialized tabulation (a 'wrapper' for -tabulate-). Each valid observation is first partitioned by varname into one of a set of 20 mutually-exclusive categories, the boundaries of which are defined by 'hard-wired' fractions of a user-specified cut-off value (in the same units as varname), with fractions ranging from 0.1 through to 3.0. This classification is then tabulated and, optionally, can be retained as a new variable. In effect xfrac provides a discrete representation of the distribution function for varname. Example: let varname be a measure of income and the cut-off be mean income. xfrac shows the proportion of observations with income less than 10% of mean income, between 10% and 20% of mean income, between 20% and 30% of mean income, and so on (20 categories). Cumulative proportions are also shown.
