each variable in varlist.


Syntax
          mdesc varlist [if] [in] [, abbreviate(#) any all none ]

by may be used with mdesc; see by.


Description

Produces a table with the number of missing values, total number of cases, and
percent missing for each variable in varlist. mdesc works with both numeric and
string variables.

Options

    abbreviate(#) abbreviate variable names to # of characters; default is
        ab(12).

    any specifies to check how many observations have at least one missing
        value for any of the specified variables.

    all specifies to check how many observations have missing values for all
        of the specified variables.

    none specifies to check how many observations have no missing values for
        any of the specified variables.

Saved Results

    The mdesc command saves scalars and macros:

      r(percent)          percent missing for last variable specified in
                            mdesc
      r(total)            total number of observations submitted to mdesc
      r(miss)             number of missing values for last variable
                            specified in mdesc

    Local Macros   
                          (when options any, all, or none are not specified)
      r(notmiss_vars)     list of variables that have no missing values that
                            were specified in mdesc
      r(miss_vars)        list of variables that have missing values that
                            were specified in mdesc
