{hi:bitowt} {hline 2} Convert binary frequency records to frequency weighted
data


{title:Syntax}

{title:Description}

{pstd}
{cmd:bitowt} converts binary frequency records to frequency weighted data.
{it:case#_var} specifies the variable containing the number of cases
represented by each observation and {it:pop_var} specifies the number of
subjects (cases plus controls) represented by each observation. This command
will change the data in memory.


{title:Options}

{phang}
{cmd:case(}{it:newvarname}{cmd:)} specifies the name of a new binary
variable containing 1 for cases and 0 for controls.  If {cmd:case()} is not
specified, {cmd:case(_case)} is assumed.

{phang}
{cmd:weight(}{it:newvarname}{cmd:)} specifies the name of a variable
that will contain frequency weights.  If {cmd:weight()} is not specified,
{cmd:weight(_weight)} is assumed.
