Then is called a pivotal quantity (or simply a pivot). Pivotal quantities are commonly used for normalization to allow data from different data sets to be compared. It is relatively easy to construct pivots for location and scale parameters: for the former we form differences so that location cancels, for the latter ratios so that scale cancels.
A ancillary statistic is a specific case of a pivotal quantity that is computed only from the data and not from the parameters. They can be used to construct prediction intervals. They are also used in connection with Basu's theorem to prove independence between statistics. [4]
The pivotal method is based on a random variable that is a function of both the observations and the parameters but whose distribution does not depend on the parameter. Such random variables are called pivotal quantities. By using these, probability statements about the observations and parameters may be made in which the probabilities do not ...

Most frequently, t statistics are used in Student's t-tests, a form of statistical hypothesis testing, and in the computation of certain confidence intervals. The key property of the t statistic is that it is a pivotal quantity – while defined in terms of the sample mean, its sampling distribution does not depend on the population parameters, and thus it can be used regardless of what these ...
Speed - Messiah has OpenGL playback and real-time previewing of fully subdivided models, particle systems and dynamics objects. [1] [2]Flexibility - Messiah offers modular interoperability with many major packages, allowing users to make animation modifications in either messiah:studio or a host program and see instant feedback and updates in the other package.

Synfig Studio (also known as Synfig) is a free and open-source vector-based 2D animation software. [3] It is created by Robert Quattlebaum [4] with additional contributions by Adrian Bentley. Synfig began as the custom animation platform for Voria Studios (now defunct), [5] and in 2005 was released as free/open source software, under GNU GPL-2. ...
