R: Fits a Multi-Modal Mallows' model to ranking data.

Mallows {RMallow} | R Documentation

## Fits a Multi-Modal Mallows' model to ranking data.

### Description

Fits the Multi-Modal Mallows' model to partial or full ranking data, using Kendall's metric and an EM algorithm. This is essentially metric sequence clustering.

### Usage

      Mallows(datas, G, iter = 10, hyp = NULL,
        plot.like = FALSE)

### Arguments

`datas` | Matrix of partial or fully-ranked data.
`G` | Number of modes, 2 or greater.
`iter` | Maximum number of iterations.
`hyp` | Hypothesis sequence vector, to initialize one of the cluster centers at.
`plot.like` | Should the likelihood be printed at each iteration?

### Value

See output of FormatOut
