Probability-Distributions

基本的な分布がそろっており、非常にシンプルで使いやすいように感じます。 手元さっと確率計算するにはとても便利です。

Subject line says it all. P(Z<x) for normal and a bunch more for essential statistical tests. THANK YOU!!!!

absolutely love this man, great for checking work and giving hints to solutions!

I love probability distributions.

I met my wife because of this app. Needless to say I’m not happy and it’s this apps fault.

Works perfectly now. Much better than using tables.

Goat status: 100%

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.

Easy my learning

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.
