Enclosing class:

NonlinearityTests

public static final class NonlinearityTests.TestResult
extends Object

Encapsulates the result of a statistical test, including the test statistic, p-value, and the decision to reject the null hypothesis. This class is immutable and provides information about the outcome of a hypothesis test.

Field Details

statistic

public final double statistic

Represents the value of the test statistic computed during a statistical hypothesis test. This value is used to determine the evidence against the null hypothesis based on the context of the test being performed. The interpretation of this value depends on the specific test type and its corresponding distribution.

pValue

public final double pValue

Represents the p-value of a statistical hypothesis test. The p-value is the probability of observing a test statistic as extreme as, or more extreme than, the one observed, under the assumption that the null hypothesis is true. It quantifies the strength of evidence against the null hypothesis. A smaller p-value indicates stronger evidence against the null hypothesis. If the p-value is not applicable or cannot be computed, this value is set to NaN.

reject

public final boolean reject

Indicates whether the null hypothesis of the statistical hypothesis test is rejected.

Constructor Details

TestResult

public TestResult(double statistic,
 double pValue,
 boolean reject)

Constructs a TestResult instance with the specified test statistic, p-value, and decision on whether to reject the null hypothesis.

Parameters:

statistic - the value of the test statistic computed in the statistical hypothesis test

pValue - the p-value of the test, representing the probability of observing a test statistic as extreme as, or more extreme than, the one observed, under the null hypothesis

reject - a boolean value indicating whether the null hypothesis is rejected based on the test result

Method Details

toString

public String toString()

Returns a string representation of this TestResult instance. The returned string includes the test statistic, p-value, and the rejection decision of the null hypothesis, formatted as key-value pairs.

Overrides:

toString in class Object

Returns:

a string representation of the TestResult in the format: "stat={statistic}, p={pValue}, reject={reject}"
