{title:Description}

{pstd}
{cmd:brier} computes the Yates, Sanders, and Murphy decompositions of the
Brier Mean Probability Score.  {it:outcomevar} contains 0/1 values reflecting
the actual outcome of the experiment, and {it:forecastvar} contains the
corresponding probabilities as predicted by, say, logit, probit, or a human
forecaster.


{title:Option}

{dlgtab:Main}

{pstd}
{opt group(#)} specifies the number of groups that will be used to compute the
decomposition.  {cmd:group(10)} is the default.
