{title:Description}

{pstd}{cmd:permtab} permutes the columns of the square
crosstabulation of rowvar by colvar to maximise kappa. It is
intended for use in comparing cluster solutions where the identity
of categories from one solution to the other is only defined in
terms of membership. Kappa measures the excess of observed over
expected on the diagonal. Kappa_max is the Kappa of the best
solution, and is reported.{p_end}

{pstd}{bf:Note}: For numbers of categories much above 8 this procedure is slow and inefficient.{p_end}
