o sandwich(), vcovHC(), and vcovHAC() did not work when models were
fitted with na.action = na.exclude because the estfun() then (correctly)
preserved the NAs. This is now avoided and all functions handle the
na.exclude case like the na.omit case. (Thanks to John Fox for spotting
the problem and suggesting the solution.)
Changes in Version 2.3-1
o The estfun() methods for "survreg" and "coxph" objects incorrectly
returned the unweighted estimating functions in case the objects
were fitted with weights. Now the weights are properly extracted
and used.
Changes in Version 2.3-0
o Updated Depends/Imports: Package "zoo" is only in Imports now.
Changes in Version 2.2-10
o Added estfun() and bread() methods for ordered response models
from MASS::polr and ordinal::clm.
o Added output of examples and vignettes as .Rout.save for
R CMD check.
Changes in Version 2.2-9
o Added convenience function lrvar() to compute the long-run
variance of the mean of a time series: a simple wrapper
for kernHAC() and NeweyWest() applied to lm(x ~ 1).
o lm/mlm/glm models with aliased parameters were not handled
correctly (leading to errors in sandwich/vcovHC etc.), fixed
now.
o An improved error message is issued if prewhitening in vcovHAC()
cannot work due to collinearity in the estimating functions.
Changes in Version 2.2-8
o fixed a bug in bwNeweyWest() for "mlm" objects that only have
an intercept.
Changes in Version 2.2-7
o HC4m and HC5 estimators, as suggested by Cribari-Neto
and coauthors, have been added to vcovHC() and related
functions.
Changes in Version 2.2-6
o bug fix in estfun() method for "survreg" objects
Changes in Version 2.2-5
o estfun() methods for "hurdle"/"zeroinfl" objects can now
handle multiple offset vectors (if any)
Changes in Version 2.2-4
o new vcovHC() method for "mlm" objects. This simply
combines the "meat" for each individual regression and combines
the result.
Changes in Version 2.2-3
o new bread() method for "mlm" objects.
Changes in Version 2.2-2
o updates in estfun() methods for hurdle/zeroinfl objects.
Changes in Version 2.2-1
o documentation enhancements for new Rd parser.
Changes in Version 2.2-0
o added/enhanced bread() and estfun() methods for "rlm"
and "mlogit" objects (from MASS and mlogit, respectively).
o made vcovHC() and vcovHAC() generic with previous function
definitions as default methods.
o updated vignettes (in particular using the more convenient
tobit() interface from the AER package).
Changes in Version 2.1-0
o added bread() and estfun() methods for "hurdle"/"zeroinfl"
objects as computed by hurdle()/zeroinfl() in
package "pscl".
o fixed bread() and estfun() methods for negative binomial
"glm" objects: now dispersion = 1 is used.
Changes in Version 2.0-3
o bread() method for "lm" objects now calls summary.lm()
explicitely (rather than the generic) so that it also
works with "aov" objects.
Changes in Version 2.0-2
o Added new vcovOPG() function for computing the outer
product of gradients estimator (works for maximum
likelihood estfun() methods only).
o Scaled estfun() and bread() method for "glm" objects
by dispersion estimate. Hence, this corresponds to
maximum likelihood and not deviance methods.
Changes in Version 2.0-1
o Minor fix to bwAndrews() so that it can be easily used
in models for multivariate means.
Changes in Version 2.0-0
o A paper based on the "sandwich-OOP" vignette was accepted
for publication in volume 16(9) of Journal of Statistical
Software at
http://www.jstatsoft.org/
o A NAMESPACE was added for the package.
Changes in Version 1.9-0
o The vignette "sandwich-OOP" has been revised, extended and
released as a technical report.
o Several estfun() methods and some of the meat() functions have
been enhanced and made more consistent.
Changes in Version 1.1-1
o estfun() methods now use directly the model.matrix() method
instead of the terms() and model.frame() methods.
Changes in Version 1.1-0
o sandwich is made object-oriented, so that various types
of sandwich estimators can be computed not only for "lm"
models, but also "glm", "survreg", etc.
To achieve object orientation this various changes have
been made: a sandwich() function is provided which needs
a bread and a meat matrix. For the bread, a generic bread()
function is provided, for the meat, there are meat(),
meatHC() and meatHAC(). All rely on the existence of a
estfun() method.
o vcovHC() and vcovHAC() have been restructured to use
sandwich() together with meatHC() and meatHAC(), respectively.
o A new vignette "sandwich-OOP" has been added, explaining
the new object-orientation features.
o Various methods to bread() and estfun() have been added,
particularly for "survreg" and "coxph".
