R: The Questmotif Bicluster algorithm

BCQuest {biclust} | R Documentation

## The Questmotif Bicluster algorithm

### Description

Performs Questmotif Biclustering a Bicluster algorithm for questionairs based on the framework by Murali and Kasif (2003). Searches subgroups of questionairs with same or similar answer to some questions.

### Usage

    ## S4 method for signature 'matrix,BCQuest'
    biclust(x, method=BCQuest(), ns=10, nd=10, sd=5, alpha=0.05, number=100)
    ## S4 method for signature 'matrix,BCQuestord'
    biclust(x, method=BCQuestord(), d=1, ns=10, nd=10, sd=5, alpha=0.05, number=100)
    ## S4 method for signature 'matrix,BCQuestmet'
    biclust(x, method=BCQuestmet(), quant=0.25, vari=1, ns=10, nd=10, sd=5,
      alpha=0.05, number=100)

### Arguments

`x` | Data Matrix.
`method` | Here BCQuest, to perform Questmotif algorithm
`ns` | Number of questions choosen.
`nd` | Number of repetitions.
`sd` | Sample size in repetitions.
`alpha` | Scaling factor for column result.
`number` | Number of bicluster to be found.
`d` | Half margin of intervall question values should be in (Intervall is mean-d,mean+d).
`quant` | Which quantile to use on metric data
`vari` | Which varianz to use for metric data

### Value

Returns an object of class `Biclust`.
