Probability-Distributions

This could be really useful for students in college stats courses who are on a budget and can’t afford to buy a $100+ dollar graphing calculator. It does basic advanced functions like binomial pdf - for free. I don’t know if it does invNorm or Z-Test calculations ( possibly not) but for a calculation app that you don’t have to pay for this is pretty great and was just what I was looking for.

I’m a grad student and this has been a huge help for my stats class. It makes it easy to calculate probabilities using any distribution that I have needed. It got even better when I discovered that the app has easy links to formulas to calculate mean and variance for each distribution.

With Bognar’s easy to use app, I’m finally able to retire these back-of-the-book probability tables when teaching social statistics at FSU. It has everything I need: pdf, cdf, the inverse, slick graphical display, easy access to the underlying formulas, and a no-brainer menu system. Well done, Dr. Bognar, and thanks!

I had Bognar as a professor multiple times in college and his app always came in handy. Whether on homework or studying for actuary exams, it’s always nice to have an app that can quickly compute values, in addition to showing graphs that help visualize data.

Doesn’t try to do a lot, but what it does it does very well. Thank you for this app. (Future feature request, if you have time: Allow setting plot boundaries. e.g. for Beta, it’s sometimes illuminating to set the x bounds to (0,1).)
