citrus.thresholdCVs: Calculate model error rates

In ParkerICI/kumquat: Identification of stratifying subpopulations in Flow Cytometry Data (based on the Citrus package)

Description

Calculate model error rates at different regularization thresholds.

Usage

citrus.thresholdCVs.quick.classification(
  modelType,
  features,
  labels,
  regularizationThresholds,
  nCVFolds = 10,
  ...
)

citrus.thresholdCVs.quick.continuous(
  modelType,
  features,
  labels,
  regularizationThresholds,
  nCVFolds = 10,
  ...
)

citrus.thresholdCVs(
  modelType,
  foldFeatures,
  labels,
  regularizationThresholds,
  family,
  folds,
  foldModels,
  leftoutFeatures,
  ...
)

citrus.thresholdCVs.quick(
  modelType,
  features,
  labels,
  regularizationThresholds,
  family,
  nCVFolds = 10,
  ...
)

Arguments

modelType	Type of model to be constructed. Valid options are: pamr and glmnet.
features	Features calculated from a clustering of all samples.
labels	Endpoint labels of clustered samples.
regularizationThresholds	Thresholds for model regularization.
nCVFolds	Number of folds for quick cross-validation.
...	Other parameters passsed to model-fitting methods.
foldFeatures	List of features with each entry containing features from an independent clustering.
family	Model family. Valid options are classification and continuous.
folds	List of fold indices
foldModels	Models constructed from each fold of features.
leftoutFeatures	Features calculated for leftout samples mapped to clustered data space.

Details

If independent fold-clustering and fold-features are calculated, use citrus.thresholdCVs. If features are derived from a clustering of all samples together, use citrus.thresholdCVs.quick. See examples.

Value

Matrix of model error rates, standard error of error estimates, and false discovery rates (if possible) at supplied regularization thresholds.
