Title

    sqstat -- Describe variables generated with sq-egen functions


Syntax

     sqstatlist [varlist] [if] [in] [, replace ranks(numlist) replace
                 list_options]

      sqstatsum [varlist] [if] [in] [, summarize_options]

     sqstattab1 [varlist] [if] [in] [, tab1_options]

     sqstattab2 varname1 [varname2] [if] [in] [, tab2_options]

   sqstattabsum varname1 [varname2] [if] [in] [, format(%fmt) tabsum_options]


Description

    Commands that provide a convenient way to describe the variables
    generated with sqegen. The commands are useful because SQ-data is in long
    form, while the variables generated with sqegen refer to the sequences as
    entire entity. To further describe the new variables one might want to
    reshape the data to wide. The sqstat-commands allow to summarize,
    tabulate, and list the variables generated with the sqegen function as if
    the data were in wide format. Thereby the names of the variables
    generated with sqegen are automatically processed.

    The following sqstat programs are available:

    sqstatlist [varlist] [ , replace ranks(numlist) ]:  Lists all variables
        generated with sqegen.  With varlist only the specified variables are
        listed. replace is used to keep the listed dataset in memory. This is
        useful to produce some non-standard description (like graphs, for
        example) of the e-generated variables. ranks() is used to restrict
        the output to the most frequent sequences. Inside the parentheses a 
        numlist might be specified, which refer to the position of the
        sequences in the sorted frequency table.

    sqstatsum [varlist]: If given without the optional varlist the command
        summarizes all variables generated with the sqegen bundle. With
        varlist only the specified variables are summarized.

    sqstattab1 [varlist]: If given without the optional varlist the command
        produces one way frequency tables of all variables generated with the
        sqegen bundle. With varlist only the specified variables are used.

    sqstattabsum varname1 [varname2 ]: Summarizes all e-generated variables
        for categories of the specified variables. Option format(%fmt) allows
        to set the display format of all cells in the output. The default is
        %9.0g.

  
    sqstattab2 varname1 [varname2]]: If given without the optional varname2
        the command displays a two-way table of varname1 against all
        variables generated with the sqegen bundle. If specified with
        varname2 a two-way table of the two specified variables is displayed.


Options

    replace keeps listed data in memory.

    ranks(numlist) restricts tabulation on most frequent sequences.

    list_options are any of the options allowed with list.

    summarize_options are any of the options allowed with summarize.

    tab1_options are any of the options allowed with tabulate oneway.

    tab2_options are any of the options allowed with tabulate twoway.

    format(%fmt) specifies output format.

    tabsum_options are any of the options allowed with tabulate, summarize().
