# Discrepancy by group.

### Description

This function computes the dissimilarity-based discrepancy measure of the groups defined by the group variable. The function is a wrapper for the TraMineR `dissvar`

function.

### Usage

1 |

### Arguments

`mdis` |
a dissimilarity matrix or a |

`group` |
group variable. If |

`...` |
additional arguments passed to |

### Details

The function is a wrapper for running `dissvar`

on the different groups defined by the `group`

variable.

### Value

A vector with the group discrepancy measures.

### Note

This function is a pre-release and further testing is still needed, please report any problems.

## create the biofam.seq state sequence object from the biofam data.
data(biofam)
biofam <- biofam[1:100,]
biofam.seq <- seqdef(biofam[,10:25])
dist <- seqdist(biofam.seq, method="HAM")
## discrepancy based on non-squared dissimilarities
dissvar.grp(dist, biofam$plingu02)
## square root of discrepancy based on squared dissimilarities
sqrt(dissvar.grp(dist, biofam$plingu02, squared=TRUE))
