Detailed Description

ChiSquareDistribution class defines the interface for a univariate Chi-Square distribution (pdfs, cdfs, etc.).

ChiSquareDistribution provides access to the probability density function (pdf), the cumulative distribution function (cdf), and the inverse cumulative distribution function for a Chi-Square distribution.

The EvaluatePDF(), EvaluateCDF, EvaluateInverseCDF() methods are all virtual, allowing algorithms to be written with an abstract interface to a distribution (with said distribution provided to the algorithm at run-time). Static methods, not requiring an instance of the distribution, are also provided. The static methods allow for optimized access to distributions when the distribution is known a priori to the algorithm.

ChiSquareDistributions are univariate. Multivariate versions may be provided under a separate superclass (since the parameters to the pdf and cdf would have to be vectors not scalars).

ChiSquareDistributions can be used for Chi-Square tests.

unsigned long itk::Object::AddObserver	(	const EventObject &	event,
		Command *
	)			const [inherited]

unsigned long itk::Object::AddObserver	(	const EventObject &	event,
		Command *
	)			[inherited]

Allow people to add/remove/invoke observers (callbacks) to any ITK object. This is an implementation of the subject/observer design pattern. An observer is added by specifying an event to respond to and an itk::Command to execute. It returns an unsigned long tag which can be used later to remove the event or retrieve the command. The memory for the Command becomes the responsibility of this object, so don't pass the same instance of a command to two different objects

static void itk::LightObject::BreakOnError

[static, inherited]

This method is called when itkExceptionMacro executes. It allows the debugger to break on error.

static double itk::Statistics::ChiSquareDistribution::CDF	(	double	x,
		long	degreesOfFreedom
	)			[static]

Static method to evaluate the cumulative distribution function (cdf) of a Chi-Square with a specified number of degrees of freedom. The static method provides optimized access without requiring an instance of the class.
