expExtract

Extract statistically equivalent methods from a multiple comparison test

Usage

expExtract(ph)

Arguments

ph
A testMultipleControl test object

Value

an experiment object

Description

This functions generates a new experiment incluing the methods that obtained an equivalent performance with statisticall significance in the multiple comparison test i.e. those whose hypotheses were not rejected

Examples

# First we create an experiment from the wekaExperiment problem and prepare # it to apply the test: experiment <- expCreate(wekaExperiment, name="test", parameter="fold") experiment <- expReduce(experiment, "fold", mean) experiment <- expInstantiate(experiment, removeUnary=TRUE) # Then we perform a testMultiplePairwise test procedure test <- testMultipleControl(experiment, "trainingTime", "min") expExtract(test)
#Experiment name: test #method: J48,no, NaiveBayes,no, OneR,no, RandomForest,no, J48,yes, NaiveBayes,yes, OneR,yes, RandomForest,yes #problem: anneal, audiology, balance-scale, car, glass, horsecolic, hypothyroid, ionosphere, liver-disorders, lymph, primary-tumor, soybean, vehicle, vote, vowel #parameters: *) featureSelection [no,yes] (instantiated) #outputs: accuracy, trainingTime
