{title:Description}

{pstd}
{cmd:yvo} performs a test of the consistencies of each configuration entered in
{it:configurations} with the outcome versus the consistency of all other
configurations. The "all other" configuration score is computed by taking the
maximum value of every configuration except for the configuration to be tested.
The configurations do not need to exist in the dataset, but their individual
single, capital letter versions must exist.


{title:Options}

{p 4 8 2}
{cmd:sigonly} displays only those configurations that have significantly
different consistencies.	

{p 4 8 2}
{opt slevel(#)} changes the significance level to be used in determining 
{cmd:sigonly}.  The default is {cmd:slevel(.05)}.

{p 4 8 2}
{cmd:greater(col1} | {cmd:col2)} displays only those configurations in which
the specified column value is greater than the other column value.  
{cmd:col1} is always the consistency with the outcome, while {cmd:col2} is the
consistency of the "all other" configuration.

{p 4 8 2}
{cmd:last} uses the outcome variable and configurations (or sets) from the last
run {cmd:fuzzy} or {cmd:settest} option call as {it:outcomevar} and
{it:configurations}.  When this option is specified, {it:outcomevar} and
{it:configurations} should not be entered. Specifically, it uses the last
displayed set of configurations.  Thus, when using this option, a
{cmd:settest()} option must have been invoked on the last call to {cmd:fuzzy}
or just run as a stand-alone command.  When {cmd:last} is used, only those last
displayed configurations will be used in the test. 

{p 4 8 2}
{cmd:usereduction} uses the outcome variable and reduced configurations from
the last run {cmd:reduce} command for the consistency test.	       

{pstd}
Note: The "all other" configuration is calculated using the set of
configurations entered. Thus, if a limited set of configurations is used, each
of the configurations will be tested against all others in this set.

{p 4 8 2}
{opt cluster(varname)} allows the standard errors produced by the {cmd:ratio}
command when calculating consistencies to adjust for intragroup correlation.
This is used in the computation of the consistency scores.
