{title:Description}

{pstd}
{opt tabulate} produces one-way tables of frequency counts.

{pstd}
For information on two-way tables of frequency counts along with measures of
association, including the common Pearson chi-squared, the likelihood ratio
chi-squared, Cram{c e'}r's V, Fisher's exact test, Goodman and Kruskal's
gamma, and Kendall's tau-b, see {help tabulate twoway}.

{pstd}
{opt tab1} produces a one-way tabulation for each variable specified in {varlist}.

{pstd}
Also see {helpb table} and {helpb tabstat} if you want one-, two-, or n-way
tables of frequencies and a wide variety of statistics.  See
{help tabulate summarize} for a description of {opt tabulate} with the
{opt summarize()} option; it produces tables (breakdowns) of means and
standard deviations.  {opt table} is better than
{cmd:tabulate, summarize()}, but {cmd:tabulate, summarize()} is faster.
See {help epitab} for 2 x 2 tables with statistics of interest to
epidemiologists.


{title:Options}

{dlgtab:Main}

{phang}
{opth subpop(varname)} excludes observations for which {it:varname} = 0 in
tabulating frequencies.  The mathematical results of {cmd:tabulate ..., subpop(myvar)}
are the same as {cmd:tabulate ... if myvar != 0}, but the table may be
presented differently.  The identities of the rows and columns will be
determined from all the data, including the {it:myvar} = 0 group, so there may
be entries in the table with frequency 0.

{pmore}
Consider tabulating {opt answer}, a variable that takes on values 1, 2, and 3,
but consider tabulating it just for {cmd:male==1} subpopulation.  Assume that
{opt answer} is never 2 in this group.  {cmd:tabulate answer if male==1}
produces a table with two rows: one for answer 1 and one for answer 3.  There
will be no row for answer 2 because answer 2 was never observed.
{cmd:tabulate answer, subpop(male)} produces a table with three rows.  The row
for answer 2 will be shown as having 0 frequency.

{phang}
{opt missing} requests that missing values be treated like other values
in calculations of counts, percentages, and other statistics.

{phang}
{opt nofreq} suppresses the printing of the frequencies.

{phang}
{opt nolabel} causes the numeric codes to be displayed rather than the
value labels.

{phang}
{opt plot} produces a bar chart of the relative frequencies in a
one-way table. (Also see {helpb histogram}.)

{phang}
{opt sort} puts the table in descending order of frequency (and
ascending order of the variable within equal values of frequency).

{dlgtab:Advanced}

{phang}
{opth generate(varname)} creates a set of indicator variables
reflecting the observed values of the tabulated variable.
The {opt generate()} option may not be used with the {opt by} prefix.

{phang}
{opt matcell(matname)} saves the reported frequencies in
{it:matname}.  This option is for use by programmers.

{phang}
{opt matrow(matname)} saves the numeric values of the r x 1
row stub in {it:matname}.  This option is for use by programmers.
{opt matrow()} may not be specified if the row variable is a string.


{title:Examples}

{phang}{cmd:. tabulate mpgcat}

{phang}{cmd:. tabulate mpgcat, generate(mpg)}

{phang}{cmd:. tabulate region [freq=pop]}

{phang}{cmd:. tab1 sex race age}
