Inequality Calculator
Given two random variables X and Y, this application calculates P(X > Y + δ)
and produces graphs of the densities of the two random variables. The supported
distribution families are
- Beta
- Gamma
- Inverse Gamma
- Log normal
- Normal
- Weibull
What's New in Version 3.1.0.0
- Added capability to change the graph legend for the X and Y Distributions
- Several minor bug fixes
Requirements
- Windows 7
(other Windows versions may be compatible but this has not been tested)
- Administrative permissions may be required to install Inequality Calculator depending
on the chosen installation location.
- The following packages will be installed if they are not present:
- Microsoft .NET Framework 4
- Microsoft Visual C++ 2013 x86 runtime redistributable library
- Microsoft Windows Installer 4.5
- To view the the
Inequality Calculator user's guide a PDF file viewer (not included with the
software) such as Adobe Reader (available for free
here) must be installed.
- To follow the "Send feed back via email" link in the Help -> About
window, an email client such as Microsoft Outlook (not included with the software)
must be installed.

This software is included as a utility inside
Adaptive Randomization,
Predictive Probabilities, and
Multc Lean.
J. Kyle Wathen and Hoang Q. Nguyen developed the original user interface using
Microsoft's C# .
John Cook implemented the numerical
algorithms using Visual C++. Technical reports are available for numerical algorithms
[1] and analytical results [2] related to the Inequality Calculator.
