### Description

The *U quadratic distribution* is defined by the following density function

where the relation between the two pairs of parameters (domain-support, a and b) and (range/offset α and β) are given by the following two equations

More information about U-quadratic, and other continuous distribution functions, is available at Wikipedia.

### Interactive U Quadratic Distribution

You can see the interactive *U Quadratic* distribution by going to SOCR Distributions and selecting from the drop down list of distributions *U Quadratic*. Then follow the **Help** instructions to dynamically set parameters, compute critical and probability values using the mouse and keyboard.
