function to derive class predictions
from conditional class
probabilities to Binomial()
family.

(closes #102).
Removed deprecated argument LINPACK
from all calls to solve
.
Fixes #109.
Fixed minor bug in plot.cvrisk
.
Fixes #96.
Really check for leave-one-out crossvalidation if CoxPH
was
used.
Fixed minor bug in documentation: ...
was described in
documentation but was not used in function.
Fixes #105.
Fixed a minor issue with special contrast "contr.dummy"
.
Fixed typo in vignette.
Dropped \itemize
in ‘ins/NEWS.Rd’.
Fixes #94.
Added family RCG
for ratio of correlated gammas and downstream test,
see Weinhold et al. (2016).
Closes #86.
Removed corrected cross-validation for Cox models (Verweij and van Houwelingen, 1993) as it was not working. Closes #85.
Use partykit::ctree
instead of party::ctree
in
btree
and blackboost
. This is slower but more flexible.
Allow multivariate negative gradients. Note that all elements are updated simultaneously, which in most cases is NOT what you want (but in rare cases it is the right thing to do).
Allow the specification of either mstop
or grid
in stabsel
.
Allow leave-one-out crossvalidation (via type = "kfold"
).
Throw error when data is not compatibel (instead of silently recycling the vector). Fixes #79.
Fixed handling of offset
for families NBinomial
and Hurdle
.
Closes #88.
Replace cBind
(now deprecated) with cbind
.
Fixes #90.
Fix predict
with zero iterations (names were not correctly assigned).
Fixes #87.

Added further tests / checks.
Removed unused functions (response
) and arguments

for the defined degrees of freedom). Changes proposed by Benjamin
Christoffersen.
Updated kernel boosting reference. Closes #84.
Rebuilt package with LF instead of CRLF to fix ‘cleanup’ script as requested by CRAN. Fixes #82
Use "old" definition of degrees of freedom in
vignette("mboost", package = "mboost")
to make results reproducible.
Fix handling of missing values in mboost
and gamboost
when weights are specified. Fixes #80.
Models with zero steps (i.e., models containing only the offset) can now be fitted. Furthermore, cross-validation can now also select a model without base-learners. Fixes #64, #66, and #69.
Binomial
now uses link functions by making use of make.link
.
Furthermore, an alternative implementation of Binomial
models
along the lines of the glm
implementation can be used via
Binomial(type = "glm")
. Additionally, it works not only with a
two-level factor but also with a two-column matrix containing the number
of successes and number of failures.
Fixes #34,
#63 and
#65.
Added new base-learner bkernel
for kernel boosting as described in
S. Friedrichs, J. Manitz, P. Burger, C.I. Amos, A. Risch, J.C. Chang-Claude, H.E. Wichmann, T. Kneib, H. Bickeboeller, and B.

Resolves issue #14.
bbs
and bmono
no longer allow data outside of
the boundary.knots
during model fitting.
Predictions for bbs

).
Better handling of errors in (single) folds of cvrisk
:
results of folds without errors are used and a warning
is
issued.
Parallel computing via mclapply
: Set
mc.preschedule = FALSE
per default.
Added new option options(mboost_check_df2lambda =
TRUE)
, which controls if a stability check in df2lambda
is performed. If set to FALSE
this might speed up the
computation of df2lambda
especially with large design
matrices.
Prediction now also possible with newdata = list()
.
Resolves issue
#15.
PropOdds()
: Updated manual for proportional odds model.
Multinomial()
: Updated manual for multinomial logit
model. Predictions for new data are now
possible (resolves issue
#13, thanks to
Sarah Brockhaus).
‘inst/CITATION’: Added subheadings and tutorial paper.
Stopped computing the singular vectors in df2lambda
as the singular values are sufficient and as
“computing the singular vectors is the slow part for large
matrices” (proposed by Fabian Scheipl).
Fixed bug in PropOdds()
which occurred if
offset
was specified: nuisance parameters delta
and sigma
were not properly initialized (spotted by Madlene Nussbaum).

Adhere to CRAN policies regarding import of base packages (closes #9).
Export df2lambda
, hyper_bbs
and bl_lin
to make package FDboost happy. Note: These functions
usually should not be called directly by users.
Added Hothorn et al (2010) to ‘inst/CITATION’

Updated references (for stability selection, confidence intervals and constrained regression)
fixed ‘inst/CITATION’
Refer to news(package = "mboost")
instead of to the

Cross-validation was potentially wrong for CoxPH()
models. Users can now choose if they want the naive
cross-validation or the improved version by Verweij and van
Houwelingen (1993); (spotted by Holger Reulen <hreulen _ at _
uni-goettingen.de>)
Examples in \dontrun
are now executable and all
dependencies are properly stated in ‘DESCRIPTION’
Added confint
function to compute (bootstrap)
confidence intervals together with plot and print methods

instead of max(log(survtime))
;
offset
in CoxPH

instead;
speed up checking of manual by changing some computations (e.g. reduce
mstop
) or exclude code from checking via \dontrun{}
removed dependency on ipred (replaced with TH.data)
small improvements in manual
bbs(..., center = "spectralDecomp")
computes the spectral
decomposition of the penalty matrix and the penalized part of the
design matrix is defined by this decomposition.
Experiments show that bols(x) + bbs(x, center = "spectralDecomp")
is a little better in recovering the true underlying functions than
the default bols(x) + bbs(x, center = TRUE)
or, equivalently,
bols(x) + bbs(x, center = "differenceMatrix")
.
For bbs(x, y, center = TRUE)
or bmrf(x, center = TRUE)
,
the spectral decomposition is (and was) always used.

folder and .Rout.save
files for
vignettes from the CRAN release

is too small to select
q
variables.

to FALSE
, i.e.,
degrees of freedom are now computed from smoothing parameter
as described in B. Hofner, T. Hothorn, T. Kneib, M. Schmid (2011).

changed default for degrees of freedom in bspatial() to df = 6
added checks in bbs (and brandom) to ensure that the specified degrees of freedom are greater than the range of the (unpenalized) null space

offset to the intercept. In addition, the intercept
term is now adjusted for centered covariates.
