Whether you're a student or a professional, you'll find our easy-to-use, free-of-charge probability package indispensible.
Not only will it save you time by converting error-prone manual numerical calculations into instantaneous mouse clicks,
it will also help you gain an understanding of the shapes and properties of various probability distributions on a conceptual level.
Features include:
- Integrator to compute area under the PDF curve (i.e. probability)
- Random sampling, with mean and confidence interval
- More than 15 continuous and discrete probability distributions, including normal, χ-square, Weibull, Binomial, and Zipf (among many others).
- Customizable distribution parameters
- "Family" mode, displaying the shape of a distribution for several parameter values simultaneously
