Calculate probabilities and visualize probability distributions
Continuous probability distributions: - Normal (Gaussian) - t (Student's t) - Chi-Squared - F - Exponential - Gamma - Beta - Log-normal - Weibull - Uniform Discrete probability distributions: - Binomial - Poisson - Pascal (Negative Binomial) - Geometric - Hypergeometric - Discrete Uniform You can now calculate confidence intervals for "Both", "Middle", "Lower" and "Upper" tails. For example, if you want to find the 95% confidence interval of a Normal Distribution: 1. first select "Normal" distribution and select "Middle" 2. then enter "0.95" on the right side of the probability values 3. From and to values will be automatically calculated for you (-1.96, 1.96 in this case) Help test the beta version of iOS app https://testflight.apple.com/join/eC4zBt6z If you like the app, your review ❤️ and 5-⭐s are highly appreciated.
