Distribution Calculator
Free AppAbout Distribution Calculator
Distribution Calculator is a simple but effective calculator with which user can draw & compute statistical probability density function, cumulative density function, or its corresponding variate value.
Since this app is built on a numerical calculator, user can find a value of his formula, or draw graph of the function without leaving the app.
For example, user can input "1-normCdf(1.96,0,1)" or "0.5 x normCdf(1.96,0,1)+ 0.5 x normCdf(1.96,1,2)" into the calculator and find its answer.
In addition, user can store screenshot of the graph, manage history of previous expression entered, and define his own functions.
You can trust output of the calculator as Ephphatha Research is an ISV who is specialized in numerical and statistical computation for last decade.
Available probability distributions:
Normal or Gaussian (norm)
Student (t)
ChiSquare (chisq)
F (f)
LogNormal (lognorm)
Exponential (expon)
Pareto (pareto)
Three-parameter (translated) Weibull (weibull)
Binomial (binom)
Poisson (poisson)
Geometric (geomet)
Gumbel or Extreme Value, Type 1 (extrem)
Rayleigh (raylei)
Beta (beta)
Cauchy (cauchy)
Gamma (gamma)
Laplace (laplace)
Logistic (logis)
Uniform (unif)
Triangular (triang)

Does not have graphs. And is based on command functions with parameters.couldbe more friendly

I really like this app but the text overlaps so I have to guess what button I'm hitting. This makes to process somewhat time consuming... well it's still faster than graphing by hand.

This app is unmatched as far as i can tell among the free apps. It has utilities for all major distributions including inverse cumulative distribution functions.
