Detailed Description

Student's t-test for the equality of means

This test analyzes whether the expected value of a random variable matches a certain known value. When there is significant statistical "evidence" against this hypothesis, the test fails.

This is useful in checking whether a Monte Carlo method method converges against the right value. Because statistical tests are able to handle the inherent noise of these methods, they can be used to construct statistical test suites not unlike the traditional unit tests used in software engineering.

This implementation can be used to test two things:

1. that the illumination scattered by a BRDF model under uniform illumination into a certain direction matches a given value (modulo noise).
2. that the irradiance caused by a single light source received by a reference point within some scene matches a given value (modulo noise).
3. that the average radiance received by a camera within some scene matches a given value (modulo noise).

Member Function Documentation

addChild()

virtual void StudentsTTest::addChild ( NoriObject *  child )

inlineoverridevirtual

Add a child object to the current instance.

The default implementation does not support children and simply throws an exception

Reimplemented from NoriObject.
