### Binomial: software for the binomial probability distribution

**Binomial**is a program for illustrating the binomial probability distribution and its approximation by a Gaussian, and for calculations related to testing of hypotheses. It is available on Linux, Unix, Windows, and Mac with a graphical user interface based on the c++ toolkit Qt by The Qt Company. Features include:

- Draw a diagram for the binomial probability distribution or the cumulative distribution. Compute both distributions for a given number k of successes. Change the sample size n and probability p of success. Save the diagram as *.png.
- Illustrate σ-neighborhoods by lines (gray) and by displaying k and z. Rescale the diagram such that its convergence is apparent as n → ∞. Draw the corresponding curve of the Gaussian normal distribution (blue).
- Compute confidence intervals or intervals of rejection for a given level of significance α.
- Exercise sheets with explanations and exercises are integrated into the program, at present only for the German version. They are reproduced here.

**Binomial 2.2**of December 21, 2012. The source code is available under the GNU General Public License. Compile it yourself on Linux, Windows, or Mac after installing Qt 4-5. For your convenience, a Windows executable is included as well.
