Probability Distributions

OUTSTANDING app. Both useful and informative. Clean interface takes you to where you need to go immediately. Besides performing the distribution calculations, the app provides formulas and other relevant information about each distribution succinctly. Thank you for providing this app free of charge and without any ads.

I teach statistic class and cannot imagine doing it without this app. So easy and intuitive for students to use. Visuals are really help to understand statistical concepts. Thanks for beautiful and reliable app

Works, does the thing I needed it to do. Every time I use the hypergeometric and click on the screen it clears x. I would be more than happy to rate 5 stars if it wasn't for this little problem.

An amazing free app. Easy to use and has a wide variety of distributions. You will need to know more than the basics of probability to get the full benefit. The distributions are accurate and wonderful.

Really good. I've been reading David Spiegelhalter's book "Art of Statistics" and working through some of his examples with this excellent app. Highly recommended.

I use this every week, especially when choosing prior distributions for Stan. It has most of the univariate distributions found in the Stan, but would be ideal if it had all of them (including alternative parameterisations).

Great app and very informative, it is so direct and gives you what you need straight away. The most amazing thing is that you can check out the formulas used in calculation.

Very goods app to help me calculate the chance for each distribution. It would be great if the app contains the Uniform distribution.

Very good app for statistical use... Contain all types of probability and sampling distributions... With respective graph and moments.. Highly recommended for statisticians...

This is incredibly good. Very fluid, very responsive. Above all it's a great idea and is implemented really well.

The best, most practical app available. Great for problem solving with easy graphic display.

Very, very handy for quick calcs of chi-squared, t-test, etc. Very easy to use..

Extremely useful app, always works as expected, has plenty of distributions, very recommended!!

Amazing App... It can solve all the problems regarding probability.. I really like this app.. Thanks for developers for such an amazing app.

Really nice app, highly recommended. Just one request: can you include skewness and kurtosis when you calculate mean and variance?

Very useful in understanding probability distributions with a simple interface.

I am giving a 4 star because you get get the answer to more than 5 decimal places which makes the answer less accurate especially when needed in more than 5 decimal places

Could be great if one can enter a custom distribution. Holding a star for that. ;)

Needed to lookup some Chi Square distribution values and this app makes it really easy!

Please add photos so others can discover this awesome app!

I absolutely 💯 love this app. Thank you sir for making an app like this one that is free to try!

Love it. A handful material for recalling my memory on the models.

Awesome! Is this app open source? Is there a link? I feel like I'll lose a limb is somehow the source code is lost 😢 Thank you so much!

What I was hoping was available was access to creating a file of data observations or vector of data observations to be loaded into the selected distributions that would display the statistical moments and the shape of the distribution.

Works great, helped me pass my statistics class.

It proved very helpful for me...very huge thanks to the engineer who made this app

Great App! I wish I found it before now!

I just can't stop using it. Kudos to the developer

Really great apps, thank you so much !!

Good app to study. Thank developer.
