d 'XTGRAPH': module to produce graphs of cross-sectional time series (xt) data d d xtgraph produces graphs showing averages of a single outcome d measured at several points over time. Data must be in xt format d (see xt). Points are connected by straight lines. Separate d lines can be produced for groups defined by any categorical d variable (string or numeric). Averages that can be plotted d include arithmetic mean (mean), geometric (gm) or harmonic means d (hm), and median (median). d d KW: graphics d KW: cross section time series d d Requires: Stata version 8.0 d d d Author: Paul Seed, King's College London d Support: email paul.seed@@kcl.ac.uk d d Distribution-Date: 20120117 d f xtgraph.ado f xtgraph.hlp
