dissvar.grp {TraMineRextras}

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

dissvar.grp(diss, group=NULL, ...)

Arguments

diss

a dissimilarity matrix or a dist object.

group

group variable. If NULL a single group is assumed.

...

additional arguments passed to dissvar .

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.

Examples

## 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))
