{title:Description}

{pstd}
{cmd:clustermat} performs hierarchical cluster analysis on the dissimilarity
matrix {it:matname}.  {cmd:clustermat} is part of the {cmd:cluster} suite of
commands; see {helpb cluster}.  All of Stata's hierarchical clustering
methods are allowed with {cmd:clustermat}.  The partition clustering methods
({cmd:kmeans} and {cmd:kmedians}) are not allowed since they require the data.

{pstd}
See {helpb cluster} for a listing of all the {cmd:cluster} and 
{cmd:clustermat} commands.  The {helpb cluster dendrogram} command will
display the resulting
dendrogram, the {helpb clustermat stop} command will help in determining the
number of groups, and the {helpb cluster generate} command will produce
grouping variables.  Other useful {cmd:cluster} subcommands include:
{cmd:notes}, {cmd:dir}, {cmd:list}, {cmd:drop}, {cmd:use}, {cmd:rename}, and
{cmd:renamevar}; see {helpb cluster notes} and {help cluster utility}.


{title:Options}

INCLUDE help clustermat_hier_opts

{* assumes -generate()- option is last one in clustermat_hier_opts.ihlp}{...}
{pmore}
Some of the clustering methods can produce reversals or crossovers.  When
reversals happen, {cmd:clustermat} also creates a fourth variable with the
suffix {hi:_pht}.  This is a pseudoheight variable that is used by some of
the post-clustering commands to properly interpret the {hi:_hgt} variable.
