Changes in flexmix version 1.1-1
o The 'cluster' argument of flexmix() may now also be a matrix of
posterior probabilities.
o Fixed a bug to make size table work in case of empty clusters.
o Fixed a bug in likelihood computation for grouped observations.
o The artificial NPreg data now also have a binomial response,
added example to help("flexmix").
Changes in flexmix version 1.1-0
o The FLXglm driver now has an offset argument.
o New data set seizure as example for a Poisson GLM
with an offset.
o fitted() can be used to extract fitted values from flexmix
and FLXrefit objects.
o New accessor methods cluster() and posterior().
o The package now uses lazy loading and has a namespace.
Changes in flexmix version 1.0-0
o The package has now an introductionary vignette which can be
accessed using the command vignette("flexmix-intro"). The vignette
has been published in the Journal of Statistical Software, Volume
11, Issue 8 (www.jstatsoft.org), and the paper should be used as
citation for flexmix, run citation("flexmix") in R 2.0.0 or newer
for details.
o Several typos in help pages have been fixed.
Changes in flexmix version 0.9-1
o Adjust for R 2.0.0.
o Fixed a bug in the summary and plot methods of flexmix objects in
case of empty clusters.
o stepFlexmix takes two new arguments: `compare' allows fo find
minimum AIC/BIC solutions in addition to maximum likelihood,
`verbose' gives some information about progress.
o Use a default of verbose=0 in FLXcontrol (better in combination
with stepFlexmix).
Changes in flexmix version 0.9-0
o new summary() and plot() methods for flexmix objects
o FLXglm objects can now be automatically refit()ted to get table of
significance tests for coefficients
o new function stepFlexmix() for more automated model search
o the artificial example data now have functions to
create them and a pre-stored data sets, new function plotEll() to
plot 2d Gaussians with confidence ellipses.
o new function KLdiv() to compute Kullback-Leibler divergence of
components
o the calculation of the degrees of freedom for FLXmclust was wrong
Changes in flexmix version 0.7-1
o fixed some codoc problems (missing aliases)
First version released on CRAN: 0.7-0
