Main Functionality

Fit the model with SLOPE(), visualize the results with plot.SLOPE(), and produce predictions for new data with predict.SLOPE().

SLOPE()
Sorted L-One Penalized Estimation
plot(<SLOPE>)
Plot Coefficients
print(<SLOPE>) print(<TrainedSLOPE>)
Print Results from SLOPE Fit
summary(<SLOPE>)
Summarize SLOPE Model
print(<summary_SLOPE>)
Print Summary of SLOPE Model
predict(<SLOPE>) predict(<GaussianSLOPE>) predict(<BinomialSLOPE>) predict(<PoissonSLOPE>) predict(<MultinomialSLOPE>)
Generate Predictions from SLOPE Models
coef(<SLOPE>)
Obtain Coefficients
deviance(<SLOPE>)
Model Deviance
score()
Compute One of Several Loss Metrics on a New Data Set

Clusters

Analyze the cluster strucure from SLOPE fits

plotClusters()
Plot Cluster Structure

Model Tuning

Use cvSLOPE() to perform cross-validation for selecting the optimal regularization parameters, plot.TrainedSLOPE() to visualize the results, and refit() to fit the final model to your data set.

cvSLOPE()
Tune SLOPE with Cross-Validation
trainSLOPE()
Train a SLOPE Model
plot(<TrainedSLOPE>)
Plot Results from Cross-Validation
print(<SLOPE>) print(<TrainedSLOPE>)
Print Results from SLOPE Fit
refit()
Refit SLOPE Model with Optimal Parameters
summary(<TrainedSLOPE>)
Summarize TrainedSLOPE Model
print(<summary_TrainedSLOPE>)
Print Summary of TrainedSLOPE Model
