depmixS4 version 1.2-0 on CRAN: support for missing data

Ingmar Visser - 2012-07-04 16:52 - depmixS4 - hidden Markov model classes

Version 1.2-0 has been released on CRAN. The major change in this version is that it supports missing data in the responses (missing covariates result in an error). The vignette accompanying the package has a brief explanation of how missing data is treated within the EM algorithm and using direct optimization of the loglikelihood.

depmixS4 - version 1.1-0 on CRAN

Ingmar Visser - 2011-11-14 19:20 - depmixS4 - hidden Markov model classes

The main change in this version is that the main loop for computing the forward and backward variables has been moved into C resulting in considerable speed improvements. Depending on model specifics this results in a 2-4 fold speed increase when fitting models.

depmixS4 - version 1.0-1 submitted to CRAN

Ingmar Visser - 2010-11-25 15:15 - depmixS4 - hidden Markov model classes

A new version of depmixS4 is submitted to CRAN which fixes a number of bugs. One related to multinomial observation models with n>1 and a logit link function, and one concerning the generation of starting values.

depmixS4 - version 1.0-0 on CRAN & paper on jstatsoft.org

Ingmar Visser - 2010-09-17 12:26 - depmixS4 - hidden Markov model classes

depmixS4 has reached some form of maturity and therefore we have bumped its version number to 1.0-0. The reason for this is that the paper illustrating the possibilities of depmixS4 has now been published in the Journal of Statistical Software and can be found there: http://www.jstatsoft.org/v36/i07

Ingmar Visser - 2010-02-22 09:10 - depmixS4 - hidden Markov model classes

The 0.3-0 version of depmixS4 contains an example of a model with multivariate normal distributions on the ?makeDepmix help page and some minor improvements in code and documentation.

depmixS4 0.2-2 submitted to CRAN

Ingmar Visser - 2009-07-01 21:36 - depmixS4 - hidden Markov model classes

This new release mostly has some minor changes and an important bug fix in multinomial response models with covariates (giving odd results and violating the baseline constraint in baseline multinomial logit models).

depmixS4 version 0.2-0 now on CRAN

Ingmar Visser - 2008-07-30 17:23 - depmixS4 - hidden Markov model classes

Most important changes include addition of more GLM distributions, addition of mix class to fit mixtures and latent class models, ie without dependencies, addition of a simulate function to generate new data from (fitted) models; finally, the help files have undergone major restructuring (as well as the internal structure of R files).
