AdjustedPValueStatistic

public AdjustedPValueStatistic(java.util.Collection<? extends java.util.Collection<? extends java.lang.Number>> data,
                               double uncompensatedAlpha,

Creates a new instance of StudentizedMultipleComparisonStatistic

Parameters:

data - Data from each treatment to consider

uncompensatedAlpha - Uncompensated alpha (p-value threshold) for the multiple comparison test

adjustedAlpha - Adjusted alpha term to account for multiple comparisons

pairwiseTest - Confidence test used for pair-wise null-hypothesis tests.

Method Detail

clone

public AdjustedPValueStatistic clone()

Description copied from class: AbstractCloneableSerializable

This makes public the clone method on the Object class and removes the exception that it throws. Its default behavior is to automatically create a clone of the exact type of object that the clone is called on and to copy all primitives but to keep all references, which means it is a shallow copy. Extensions of this class may want to override this method (but call super.clone() to implement a "smart copy". That is, to target the most common use case for creating a copy of the object. Because of the default behavior being a shallow copy, extending classes only need to handle fields that need to have a deeper copy (or those that need to be reset). Some of the methods in ObjectUtil may be helpful in implementing a custom clone method. Note: The contract of this method is that you must use super.clone() as the basis for your implementation.

Specified by:

clone in interface CloneableSerializable

Overrides:

clone in class AbstractPairwiseMultipleHypothesisComparison.Statistic

Returns:

A clone of this object.

getAdjustedAlpha

public double getAdjustedAlpha()

Getter for adjustedAlpha

Returns:

Adjusted alpha term to account for multiple comparisons

getAdjustedAlpha

public double getAdjustedAlpha(int i,
                               int j)

Description copied from class: AbstractPairwiseMultipleHypothesisComparison.Statistic

Gets the adjusted alpha (p-value threshold) for the given comparison

Specified by:

getAdjustedAlpha in class AbstractPairwiseMultipleHypothesisComparison.Statistic

Parameters:

i - First treatment to compare

j - Second treatment to compare

Returns:

Adjusted alpha (p-value threshold) for the given comparison
