brglm2 0.6.2
Other improvements, updates and additions
vcov.brglmFit objects now uses vcov.summary.glm and supports the complete argument for controlling whether the variance covariance matrix should include rows and columns for aliased parameters.- Deprecated
detect_sepration and check_infinite_estimates, which will be removed from brglm2 at version 0.8. New versions of detect_sepration and check_infinite_estimates are now maintained in the detectseparation R package.
- Fixed typos in NEWS.
brglm2 0.6.1
Bug fixes
- Fixed bug in AIC reported by
print.summary for brmultinom and bracl
detect_separation now handles one-column model matrices correctly.
Other improvements, updates and additions
- Documentation improvements and typo fixes
brglm2 0.6
New functionality
brglmFit can now do maximum penalized likelihood with powers of the Jeffreys prior as penalty (type = "MPL_Jeffreys) for all supported generalized linear models. See brglmControl and brglmFit for details.
Other improvements, updates and additions
- Documentation updates and improvements.
- Updated vignettes to include maximum penalized likelihood with powers of the Jeffreys prior as penalty.
- New examples in
?brglmFit.
brglm2 0.5.2
Bug fixes
print.brmultinom is now exported, so bracl and brmultinom fits print correctly.
New functionality
- Added
response_adjustment argument in brglmControl to allow for more fine-tuning of the starting values when brglmFit is called with start = NULL.
Other improvements, updates and additions
- Documentation updates and improvements.
- Added Kosmidis et al (2019) in the description file.
- Added tests for
brglmControl.
brglm2 0.5.1
Other improvements, updates and additions
- Fixed typos in vignettes and documentation.
- Added ORCHID for Ioannis Kosmidis in DESCRIPTION.
brglm2 0.5.0
Bug fixes
brglmFit now works as expected with custom link functions (mean and median bias reduction).brglmFit respects the specification of the transformation argument in brglmControl.- Fixed bug in the computation of the QR decomposition under aliasing in
brglmFit.
- Other minor bug fixes and performance improvements.
- Protection against use of
quasi, quasibinomial and quasibinomial families and documentation update.
New functionality
- Added
bracl for fitting adjacent category logit models for ordinal responses using maximum likelihood, mean bias reduction, and median bias reduction and associated methods (logLik, summary and so on).
- Added
predict methods for brmultinom and bracl. @ Added residuals methods for brmultinom and bracl (residuals of the equivalent Poisson log-linear model)
- Added the
mis link functions for accounting for misclassification in binomial response models (Neuhaus, 1999, Biometrika).
Other improvements, updates and additions
brglm2 0.1.8
Other improvements, updates and additions
- Improved documentation examples.
- Removed warning about observations with non-positive weights from brmultinom.
- Updated email address for Ioannis Kosmidis in brglmFit.
Bug fixes
- brmultinom returns a fitted values matrix that respects the dimension of data.
- Fixed bug on condition for NA dispersion for models with 0 df resid.
brglm2 0.1.7
Other improvements, updates and additions
- Eliminated errors from markdown chunks in multinomial vignette.
brglm2 0.1.6
Bug fixes
- Compatibility with new version of enrichwith.
Other improvements, updates and additions
- New email for Ioannis Kosmidis.
brglm2 0.1.5
Bug fixes
New functionality
- Added
type = AS_mixed as an option to use mean-bias reducing score functions for the regression parameters and median-bias reducing score functions for the dispersion in models with unknown dispersion.
check_infinite_estimates now accepts brmultinom objects.- Added
singular.ok argument to brglmFit and detect_separation methods in line with the update of glm.fit.
Other improvements, updates and additions
- less strict tolerance in
brglm_control.
- Updates to help files.
- Fixed typos in iteration vignette.
- Added URL and bugreports in Description.
- Added new tests.
brglm2 0.1.4
Bug fixes
brglmControl is now exported.slowit did nothing; now included in iteration.
New functionality
- The
detect_separation method for the glm function can be used to check for separation in binomial response settings without fitting the model. This relies on a port of Kjell Konis’ safeBinaryRegression:::separator function (see ?detect_separation).
- brglm2 provides estimation via median-bias reducing score functions with
type = "AS_median".
- brglm2 provides camel and underscored aliases for basic methods (
brglmFit, brglm_fit, detectSeparation, detect_separation, brglm_control, brglmControl, detectSeparationControl, detect_separation_control, checkInfiniteEstimates, check_infinite_estimates).
Other improvements, updates and additions
- Minor enhancements in the codebase.
- The inverse expected information matrix is computed internally using
cho2inv.
- Internal changes to have more meaningful variable names.
- Renamed detect_infinite* to check_infinite.
brglm2 0.1.3
Bug fixes
New functionality
Other improvements, updates and additions
- Fixed typo in f_{Y_i}(y) in iteration vignette (thanks to Eugene Clovis Kenne Pagui for spotting),
brglm2 0.1.2
