Public Methods

Method	Description
ComputePower ( ) : void	Computes the power for a test with givens values of effect size and number of samples under IPowerAnalysis.Size.
GetEffectSize ( int sampleSize, double power = 0.8, double alpha = 0.05, OneSampleHypothesis hypothesis = OneSampleHypothesis.ValueIsDifferentFromHypothesis ) : TTestPowerAnalysis	Estimates the number of samples necessary to attain the required power level for the given effect size.
GetSampleSize ( double delta, double standardDeviation = 1, double power = 0.8, double alpha = 0.05, OneSampleHypothesis hypothesis = OneSampleHypothesis.ValueIsDifferentFromHypothesis ) : TTestPowerAnalysis	Estimates the number of samples necessary to attain the required power level for the given effect size.
TTestPowerAnalysis ( OneSampleHypothesis hypothesis ) : System	Creates a new TTestPowerAnalysis.
TTestPowerAnalysis ( TwoSampleTTest test ) : System	Creates a new TTestPowerAnalysis.
