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)
