msaenet 3.1.2
CRAN release: 2024-05-11
Improvements
- The coefficient profile plot now has a new default color palette (new Tableau 10). The updated palette offers a more refined and visually appealing look, while also improving accessibility for users with color-vision deficiencies. The color palette is consistency applied across multiple graphical elements in all plot types (#13).
- Added a note in the vignette about possible graphical parameters for labeling the selected variables supported by the plotting methods (thanks, @xingxingyanjing, #12).
- Simplified and optimized vignette and readme plotting chunk options (#14).
- Fixed typos and improved text style in documentation (#14).
msaenet 3.1.1
CRAN release: 2024-03-04
Improvements
- Used a proper, three-component version number following Semantic Versioning.
- Fixed warnings about single lambda (#11).
- Fixed “lost braces” check notes on r-devel and check notes about
LazyData. - Fixed code linting issues.
- Used GitHub Actions to build the pkgdown site.
msaenet 3.1
CRAN release: 2019-05-17
Improvements
- Added detailed signal-to-noise ratio (SNR) definition in
msaenet.sim.gaussian(). - Updated the example code in the vignette to make it work better with the most recent version of glmnet (2.0-16).
- Updated GitHub repository links due to the handle change.
- Updated the vignette style.
msaenet 3.0
CRAN release: 2018-12-14
New features
- Added a new argument
penalty.factor.initto support customized penalty factor applied to each coefficient in the initial estimation step. This is useful for incorporating prior information about variable weights, for example, emphasizing specific clinical variables. We thank Xin Wang from University of Michigan for this feedback (#4).
msaenet 2.9
CRAN release: 2018-05-14
Improvements
- New URL for the documentation website: https://nanx.me/msaenet/.
msaenet 2.8
CRAN release: 2018-01-05
New features
- Added a Cleveland dot plot option
type = "dotplot"inplot.msaenet(). This plot offers a direct visualization of the model coefficients at the optimal step.
msaenet 2.4
CRAN release: 2017-02-18
Improvements
- Improved graphical details for coefficient path plots, following the general graphic style in the ESL (The Elements of Statistical Learning) book.
- More options available in
plot.msaenet()for extra flexibility: it is now possible to set important properties of the label appearance such as position, offset, font size, and axis titles via the new argumentslabel.pos,label.offset,label.cex,xlab, andylab.
msaenet 2.3
CRAN release: 2017-02-10
Improvements
- Reduced model saturation cases and improved speed at the initialization step for MCP-net and SCAD-net based models when
init = "ridge", by using the ridge estimation implementation fromglmnet. As a benefit, we now have a more aligned baseline for the comparison between elastic-net based models and MCP-net/SCAD-net based models wheninit = "ridge". - Style improvements in code and examples: reduced whitespace with a new formatting scheme.
msaenet 2.2
CRAN release: 2017-02-02
New features
- Added BIC, EBIC, and AIC in addition to k-fold cross-validation for model selection.
- Added new arguments
tuneandtune.nstepsto controls this for selecting the optimal model for each step, and the optimal model among all steps (i.e. the optimal step). - Added arguments
ebic.gammaandebic.gamma.nstepsto control the EBIC tuning parameter, ifebicis specified bytuneortune.nsteps. - Redesigned plot function: now supports two types of plots (coefficient path, screeplot of the optimal step selection criterion), optimal step highlighting, variable labeling, and color palette customization. See
?plot.msaenetfor details.
Improvements
- Renamed previous argument
gamma(scaling factor for adaptive weights) toscaleto avoid possible confusion. - Reset the default values of candidate concavity parameter
gammasto be 3.7 for SCAD-net and 3 for MCP-net. - Unified the supported model
familyin all model types to be"gaussian","binomial","poisson", and"cox".
msaenet 2.1
CRAN release: 2017-01-15
New features
- Added functions
msaenet.sim.binomial(),msaenet.sim.poisson(),msaenet.sim.cox()to generate simulation data for logistic, Poisson, and Cox regression models. - Added function
msaenet.fn()for computing the number of false negative selections in msaenet models. - Added function
msaenet.mse()for computing mean squared error (MSE).
Improvements
- Speed improvements in
msaenet.sim.gaussian()by more vectorization when generating correlation matrices. - Added parameters
max.iterandepsilonfor MCP-net and SCAD-net related functions to have finer control over convergence criterion. By default,max.iter = 10000andepsilon = 1e-4.
msaenet 2.0
CRAN release: 2017-01-05
New features
- Added
amnet()to support adaptive MCP-net. - Added
asnet()to support adaptive SCAD-net. - Added
msamnet()to support multi-step adaptive MCP-net. - Added
msasnet()to support for multi-step adaptive SCAD-net. - Added
msaenet.nzv.all()for displaying the indices of non-zero variables in all adaptive estimation steps.
msaenet 1.1
CRAN release: 2016-12-29
New features
- Added method
coeffor extracting model coefficients. See?coef.msaenetfor details.
