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

Description

#' Get regularization thresholds of pre-selected cross-validation points and their indicies.

Usage

citrus.getCVMinima(modelType, thresholdCVRates, fdrRate = 0.01)

Arguments

modelType	Method to be used for model-fitting. Valid options are: glmnet,pamr, and sam.
thresholdCVRates	Matrix of error rates at regularizationThresholds returned by citrus.thresholdCVs.* function.
fdrRate	FDR Maximum used to determine FDR-constrained model regularization threshold.

Details

For predictive models (i.e. pamr or glmnet), returns indicies of regularization thresholds producing the minimum cross validation error rate (cv.min), the simplest model having error within 1 standard error of the minimum (cv.1se), and the model with the minimum error having an FDR rate < fdrRate (cv.fdr.constrained) when possible.

Value

List of regularization thresholds and indicies based on pre-selected cross-validation error rates points.
