# clmconf(1)

create confidence measures for individual nodes and clusters

## NAME

clmconf - create confidence measures for individual nodes and clusters

## SYNOPSIS

**clmconf** \<options\>

options, all obligatory:

**-icl** \<fname\> (*input cluster file*)\
 **-imx** \<fname\> (*input matrix/graph file*)\
 **-ncm** \<fname\> (*output node confidence file*)\
 **-ccm** \<name\> (*output cluster confidence file*)

## DESCRIPTION

**clmconf** shows how well each node fits in the cluster it is in and how cohesive each cluster is. This lets you compare the quality of the clusters in a clustering relative to each other, and may help in identifying both interesting areas and areas for which cluster structure is hard to find or perhaps absent.

**clmconf** abuses the **mcl** matrix format a little by using it for storing tables.

The **node confidence matrix**, stored in the file specified by the **-ncm** option, has the following structure. The columns range over all elements in the graph as specified by the **-imx** option. Each row consists of two elements only, confiding characteristics of *c* relative to the graph and the clustering specified by the **-icl** option. Given a node *c*, the entry in row zero shows the mass fraction of edges that have *c* as tail and for which the head is in the same cluster as *c*, relative to the mass of all edges that have *c* as tail. The entry in row one lists the number of edges originating from *c*.

The **cluster confidence matrix**, stored in the file specified by the **-ccm** option, has the following structure. The columns range over all clusters in the clustering as specified by the **-icl** option. Each row consists of two elements. Given a cluster *C*, the entry in row zero shows the average of the node confidence (defined above) for all nodes *c* in *C*. The entry in row one lists the number of nodes in *C*.
