BCQuest {biclust}

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
