Description Usage Arguments Value
View source: R/mboost_diff_Rsq.R
This function provides importance scores for variables (including the knockoffs) in order to compute statistics. The variable importance is measured by R-squares obtained from boosting.
1 | stat.mboost_diff_Rsq(Xaug, y, max.mstop = 100, bl = c("bbs", "bols", "btree"), cv.fold = 5, family = Gaussian())
|
Xaug |
augmented design matrix combining original predictors and knockoff variables |
y |
response vector, or a survival object with two columns |
max.mstop |
maximum number of boosting iteration |
bl |
base-learners when fitting models using mboost. 'bols' means linear base-learners, 'bbs' penalized regression splines with a B-spline basis, and 'btree' boosts stumps. |
cv.fold |
number of folds in cross-validation to choose number of iteration |
family |
Binomial(), Binomial(link = <e2><80><9c>logit<e2><80><9d>, type=<e2><80><9d>glm<e2><80><9d>), Gaussian(), Poisson(), CoxPH(), Cindex(), GammaReg(), NBinomial(), Weibull(), Loglog(), Lognormal(), etc. See mboost documentation for details. |
2p vector containing varible importance for both orginal variables and knockoff variables
