[Traminer-users] how to get representative sequence by using multichannel method

[Gilbert Ritschard]

Hi Mira,

I forgot there is a TraMineR dissrep function that searches for representatives from any dissimilarity matrix. You could use it to get representatives of multichannel sequences.  However, there is no plot function for the resulting outcome.

Best.

Hi Mira,

Sorry for this late answer.

Currently you cannot get representative multichannel sequences.

The algorithm used for searching for the representative sequence(s) requires only the dissimilarity matrix. It should therefore be applicable to a dissimilarity matrix of multichannel sequences. However, the seqrep function that implements it requires also a state sequence object that is used for printing the results. It does not know how to handle the list of the multichannel state sequences. Actually, the print and plot function for the object returned by seqrep work only with single channel sequences.

A solution could be to transform the multichannel sequences into combined single sequences and pass the resulting sequence object to seqrep together with the dissimilarity matrix computed using seqdistmc.

Best.
Gilbert

Dear tramier-users

Can I get representative sequence by using multichannel method?
I am trying to analyze couple's time schedules.
If I use multichannel distance matrix (getting by "seqdismc" using list: male & female sequences), "seqrep" would resurns it?

I just guess it will be differently affected according to criterion sorting representative candidate list such as "freq", "dist"...
"dist" is about centrality having the smallest sum of the distances to all othere sequences,
Then can I think it will be affected just by distance matrix for returning representative?


best,

Mira
