Dear R users,
The PST package (version 0.81) is now available on the CRAN. It enables
the modelling and analysis of categorical sequences with probabilistic
suffix trees (PST).
The package fits variable length Markov chain models and store them in
PSTs. It is specifically adapted to the field of social sciences by
allowing to learn VLMC models from sets of individual sequences possibly
containing missing values, and to account for case weights.
Fitted PSTs can be used among other for sequence prediction (pattern
mining), imputation and artificial sequences generation. The package
also includes original visualization tools of both the model and
outcomes of sequence prediction.
