Variable-modifying options for parmest and parmby


Syntax


    options                   Description
    -------------------------------------------------------------------------
    rename(renaming_list)     Rename variables in the output dataset
    format(formatting_list)   Display formats for variables in the output
                                dataset
    float                     Set storage type of numeric variables to float
                                or lower precision
    nodouble                  Alternative option for specifying float
    -------------------------------------------------------------------------

    where renaming_list is a list of  variable names of form

    oldvarname_1 newvarname_1 ... oldvarname_n newvarname_n

    and formatting_list is a list of form

    varlist_1 format_1 ... varlist_n format_n


Description

    These options allow the user to change the names, display formats and
    storage types of variables in the output dataset (or resultsset) created
    by parmest or parmby.


Options

    rename(oldvarname_1 newvarname_1 ... oldvarname_n newvarname_n) specifies
        a list of pairs of variable names.  The first variable name of each
        pair specifies a variable in the parmest output dataset, which is
        renamed to the second variable name of the pair.  This option may be
        used to change the names of output variables to prevent name clashes,
        especially with variables specified in the by() option of parmby,
        which cannot be renamed using the rename() option.

    format(varlist_1 format_1 ... varlist_n format_n) specifies a list of
        pairs of variable lists and display formats.  The formats will be
        allocated to the variables in the output dataset specified by the
        corresponding varlists.  If rename() is specified, then any variable
        names specified by the format() option must be the new names.

    float specifies that there will be no variables in the output dataset of
        storage type double.  If float is not specified, then all numeric
        variables in the output dataset will be of type double, and therefore
        stored to double precision, except if they can be compressed without
        loss of precision, in which case they will be compressed as far as
        possible without loss of precision.  If float is specified, then
        variables of type double in the output dataset will be converted to
        type float, even if this results in loss of precision.  (See help for
        recast.)

    nodouble is an alternative way of specifying float.


Notes

    See parmest_resultssets for details of the variables in datasets created
    by parmest and parmby.
