In this example, we do not specify the output file, so the simulated family data are saved into temp.dta. The extra variable
named marry is produced by simuped3 compared with simuped2. It indicates the marriage status of a person.

gr45 A turnip graph engine

Steven Woloshin, VA Outcomes Group, VA Medical Center, White River Junction, VT, [email protected]
Abstract: A new graphical description called a turnip graph for studying the distribution of a variable is introduced and illustrated.
Keywords: descriptive statistics, histogram, stem and leaf plot, turnip plot.

Syntax

turnip varname [if exp] [, résolut ion (#) truev(#) graph-options ]

Description

turnip creates a turnip-style graph for the variable varname. The range of the variable is divided into intervals which are
placed on the vertical axis of the plot. Symbols are plotted horizontally next to each interval reflecting the number of observations
in that interval. Thus one can use this plot in conjunction with histograms, boxplots, stem-and-leaf plots, and so on, to study the
distribution of a variable.

Options

résolut ion (#) specifies the resolution of the graph, that is, the width of the intervals to be used. The default value is 0.4s,
where
s is the standard deviation of the variable. Since resolution rounds the data, the graph in essence displays the
frequency of observations falling within each resolution unit. The user can avoid any such rounding (that is, display the
frequency of each value in the data) by specifying the resolution width as any negative number.

truev(#) specifies a value that can be used to divide a variable into three parts: one exactly equal to truev, one that is greater
than truev, and one that is less than truev. For example, suppose you are trying to display change scores and want to
show which observations are above or below zero. Using truev(0) ensures that only zero values are graphed at zero;
other values which would round to zero are set at the next appropriate category of
varname.
