## The proportion of ambiguous clustering (PAC score)

### Description

The proportion of ambiguous clustering (PAC score)

### Usage

    PAC(consensus_mat, x1 = 0.1, x2 = 0.9, class = NULL)

### Arguments

`consensus_mat` | A consensus matrix.
`x1` | Lower bound to define "ambiguous clustering".
`x2` | Upper bound to define "ambihuous clustering".
`class` | class IDs. If it is provided, samples with silhouette score less than 5th percential are removed.

### Details

The PAC score is defined as F(x2) - F(x1) where F(x) is the CDF of the consensus matrix.

### Value

A single numeric vaule.
