    File
      file(filename)         specifies the name of the file in which the

Description

    corrtex produces a correlation table in LaTeX format.  This command is
    inspired by mktab and outreg commands, and its code heavily borrows from
    mkcorr and sutex commands.  This command offers a number of advantages
    such as allowing the use of labels, controlling the number of decimal
    places used, and other LaTeX specific formatting options.

Options

        +------+
    ----+ File +-------------------------------------------------------------

    file(filename) specifies the name of the file in which the output is to
        be stored.  The output file, filename.tex, can be included directly
        in a LaTeX document.  If the user specifies a file name that includes
        an extension, that extension will be used rather than .tex.  The
        filename specification may include the path of a directory other than
        the current working directory.

    append appends the code to the specified file. This option can not be
        used in conjunction with replace.

    replace overwrites any existing file with the same name. This option can
        not be used in conjunction with append.

        +--------------+
    ----+ Table format +-----------------------------------------------------

    digits(#) defines the number of digits to be displayed (default is 3).

    landscape generates a landscape format table.

    longtable allows to create tables that span over several pages using the
        "supertabular" package (do not forget to \usepackage{longtable} in
        the preamble of your .tex document)

    na(string) allows to define the content of cells where a numerical value
        has no sense (for example a Std. Dev. for only one observation).
        ATTENTION : do not use the following characters # $ % & ~ _ ^ \ { }
        in that option.

    sig requests that the significance of each correlation be printed under
        it.

    casewise causes the table to reflect casewise deletion. In other words,
        results will reflect only those observations for which no listed
        variables are missing. This command will yield results identical to
        using corrrelate.  The default is to engage in pairwise deletion,
        yielding results identical to using pwcorr.

    nbobs displays the number of observations under each correlation.

    placement(string) specifies the placement of the table in the .tex doc
        (default is htbp)

    title(string) defines the table title (Cross-correlation table is
        default).

    key(string) defines the table label (corrtable is default).

        +--------+
    ----+ Output +-----------------------------------------------------------

    With the noscreen option, the correlation table is not displayed in the
        Result window.


Examples

    . webuse auto2yr

    . corrtex price mpg, file(auto)

    . corrtex price mpg if price>5000, file(auto) replace case sig dig(4) nb

    . bysort foreign : corrtex price mpg, file(auto) replace longtable
        title(Cross-correlations)
