[Traminer-users] Occurence of sequences and time

[Gilbert Ritschard]

Hi Zéphyrin,

For a workaround to find substrings instead of subsequences look at
http://stackoverflow.com/a/27230558/1586731

The seqeconstraint function used there also allows to control for the counting method (use CDIS for counting distinct occurrences in a same sequence).

Best.
Gilbert

Subject: [Traminer-users] Occurence of sequences and time

Hi TraMineR users,
I look at TraMineR and I wonder if someone can help me to deal with this two problems:

1. Subsequence/substring mining: I can find if a sequence contains a subsequence/substring. But I would like to know the number of occurence of subsequence/substring in a sequence.
I am interesting in the substring and not subsequence. As I know, subsequence also consider non consecutive states, but I want to consider only consecutive states.
For example, in the sequence A-B-A-C-B-A-C-A-B-A, I would like to have 3 as the number of B-A in the sequence.

2. Time: TraMineR consider the time as the time when the event occurs or when the state is reaches. Am I wrong?
I would like to consider the time spent (duration) in a state. AAs the duration (in sec. for example) can be a "double"  (e.g., 4.73), is there any way to mine sequences with states/events duration?

Thanks in advance for your help.
Zéphyrin.
