Changes in Version 0.3-1
o Improvements for 'prunepath' method.
o Moved documentation of 'prunepath' to 'tvcm-assessment'.
o Added example for 'prune'.
o Internal changes in 'estfun.olmm' and new argument 'center' for
the function 'predecor_control'.
o New argument 'fast' for 'tvcm_control' to control whether an
approximative or the accurate model is used at exhaustive search.
o Corrected bugs in 'tvcm_exsearch_nomToOrd' and 'tvcm_getNumSplits'
which appeared in in special cases.
o Improved help manual for 'tvcglm' and 'tvcolmm'.
o Revised references.
Changes in Version 0.2-3
o Added contr.wsum function.
o Added 'seed' argument to 'otsplot_control'.
o Internal changes for exhaustive search of 'tvcm'.
o Improved documentation.
Changes in Version 0.2-2
o Added seed option to 'tvcm_control'.
o The new implementation clearly distinguishes between the two
functions 'tvcolmm' and 'tvcolmm' with separate help files.
The general function 'tvcm' is still available.
o Added convenience function 'tvcolmm_control' and
'tvglm_control'.
o Improvement for 'panel_coef': Points and lines surpassing
the boxes are now suppressed.
o Added variable centering as default for split selection.
o Redefinition of tuning parameters for 'tvcm'. The main
tuning parameter is now 'cp'. See the help of 'tvcm' and
'tvcm_control' for details.
o Added 'nimpute' argument for 'tvcm_control'.
o Added detail section to the help page of 'tvcm_control'.
o Removed AIC table from 'print.tvcm' (AIC and BIC seem not
relevant measures for models fitted by 'tvcm').
o Added 'PL' data set.
o Removed bug for numeric estimation of covariance of 'olmm'
objects.
o Added 'depth' and 'width' methods.
Changes in Version 0.2-1
o First CRAN release.
o 'tvcm' and 'fvcm' allow for multiple 'vc' terms, i.e.
coefficient-specific partitions.
o Complete revision of syntaxes, argument names and default
parameters. R commands for the former version 0.1-14 are
hardly compatibel. Please contact <rbuergin@gmx.ch>
in case of questions.
o The default splitting criterion of 'tvcm' was changed from
(old) coefficient constancy tests combined with greedy loss
minimization to (new) exhaustive greedy loss minimization. Splitting
based on the (old) requires to set the argument 'sctest = TRUE' in
'tvcm_control'.
o The greedy loss reduction minimization stage of 'tvcm' does now
fixate coefficients which are not splitted at the estimates of
the current model. The technique intends acceleration.
o Cross-validation is now integrated in the 'tvcm' function.
o 'cvloss' and 'prune' are parallelized using the 'parallel' package.
