%description
Cross validation informed Relaxed LASSO (or more generally elastic net),
gradient boosting machine ('xgboost'), Random Forest ('RandomForestSRC'),
Oblique Random Forest ('aorsf'), Artificial Neural Network (ANN),
Recursive Partitioning ('RPART') or step wise regression models are fit.
Cross validation leave out samples (leading to nested cross validation) or
bootstrap out-of-bag samples are used to evaluate and compare performances
between these models with results presented in tabular or graphical means.
Calibration plots can also be generated, again based upon (outer nested)
cross validation or bootstrap leave out (out of bag) samples. For some
datasets, for example when the design matrix is not of full rank, 'glmnet'
may have very long run times when fitting the relaxed lasso model, from
our experience when fitting Cox models on data with many predictors and
many patients. This may be remedied by using the 'path=TRUE' option, which
is passed to the glmnet() and cv.glmnet() calls. Other packages doing
similar include 'nestedcv' <https://cran.r-project.org/package=nestedcv>,
'glmnetSE' <https://cran.r-project.org/package=glmnetSE> which may provide
different functionality when performing a nested CV. Use of the 'glmnetr'
has many similarities to the 'glmnet' package and it could be helpful for
the user of 'glmnetr' also become familiar with the 'glmnet' package
<https://cran.r-project.org/package=glmnet>, with the "An Introduction to
'glmnet'" and "The Relaxed Lasso" being especially useful in this regard.
