CHANGES in `mboost' VERSION 0.5-3 (2007-03-23)
o predict() for gamboost(..., dfbase = 1) was not working correctly
o small performance and memory improvements for glmboost()
CHANGES in `mboost' VERSION 0.5-2 (2007-02-28)
o some performance improvements for `glmboost()'
o blackboost() is now generic with formula and x, y interface
o plot() method for cvrisk() and AIC() output now allows for ylim
specification without troubles
CHANGES in `mboost' VERSION 0.5-1 (2007-02-02)
o depends party 0.9-9
CHANGES in `mboost' VERSION 0.5-0 (2007-01-30)
o new `baselearner' argument to `gamboost' allowing to
specify difference component-wise base-learners to
be used. Currently implemented: "ssp" for smoothing splines
(default), "bsp" for B-splines and "ols" for linear models.
The latter two haven't been tested yet.
o The `dfbase' arguments now applies to each covariate and
no longer to each column of the design matrix.
o cvrisk() for blackboost() was broken, totally :-(
o centered covariates were returned by glmboost() and gamboost()
o Poisson() used an incorrect offset
o check for y being positive counts when family = "Poisson()"[B
o checks for Poisson() logLik() and AIC() methods
o fire a warning when all u > 0 or u < 0
o update vignette `mboost_illustrations'
CHANGES in `mboost' VERSION 0.4-17 (2007-01-15)
o fix problem with `dfbase' in `gamboost', spotted by
Karin Eckel <Karin.Eckel@imbe.imed.uni-erlangen.de>
CHANGES in `mboost' VERSION 0.4-16 (2007-01-12)
o work around stats4:::AIC
CHANGES in `mboost' VERSION 0.4-15 (2006-12-06)
o fix plot problems in plot.cvrisk
o allow for centering of the numerical covariates in glmboost and
gamboost
CHANGES in `mboost' VERSION 0.4-14 (2006-10-27)
o AIC(..., "classical") is now faster for non-gaussian families
CHANGES in `mboost' VERSION 0.4-13 (2006-10-04)
o predict(..., newdata) can take a matrix now
CHANGES in `mboost' VERSION 0.4-12 (2006-09-13)
o predict(<blackboost-object>, type = "response") did not return
factors when the response was actually a factor
o report offset in print methods
o add offset attribute to coef.glmboost
CHANGES in `mboost' VERSION 0.4-11 (2006-09-07)
o add `contrasts.arg' argument to `glmboost.formula'
o more meaningful default for `grid' in `cvrisk'
o R-2.4.0 fixes
CHANGES in `mboost' VERSION 0.4-10 (2006-08-30)
o add checks for CoxPH (against coefficients and logLik of coxph)
o add weights to CoxPH
o the ngradient function in Family objects needs to implement
arguments (y, f, w), not just (y, f)
o check for meaningful class of the response for some families
CHANGES in `mboost' VERSION 0.4-9 (2006-07-17)
o some small speed improvements in `gamboost'
o handle factors in `gamboost' properly (via a linear model)
o the dfbase argument can take a vector now (in `gamboost')
o update and improve entries in DESCRIPTION
o documentation updates
CHANGES in `mboost' VERSION 0.4-8 (2006-07-05)
o Huber() is `Huber Error', not `Huber Absolute Error'
o added `CoxPH' family object for fitting Cox models
o remove inst/LaTeX
o use NROW / NCOL more often (now that `y' may be a `Surv' object)
o implement `cvrisk', a general cross-validation function for the
empirical risk and a corresponding plot method
o unify risk computations in all three fitting functions
o unify names for `gb' objects
o allow for out-of-bag risk computations
o some cosmetics
o update keywords in Rd-files
o risk was always 0 in Huber()@risk when d was choosen adaptively
o pData(westbc)$nodal.y has levels `negative' and `positive'
(lymph node status)
CHANGES in `mboost' VERSION 0.4-7 (2006-06-19)
o add src/Makevars (required for Windows builds)
o make sure objects that are modified at C-level get _copied_ in
`blackboost'
CHANGES in `mboost' VERSION 0.4-6 (2006-06-14)
o some minor `codetools' fixes: removed unused variables
and an out-dated function
o add `codetools' checks to regression tests
o fix xlab in plot.gbAIC
