| There are two parts:
Continuous distribution functions:You can calculate cumulative distribution functions and their inverse functions,
generate tables and random numbers.
For the discrete random variables it is possible to
calculate probability, cumulative probability functions and tables.
||New: It is possible to generate random numbers. You can use them with Copy and Paste.
| You must use the decimal point!
|| As input simple numbers but also mathematical more complex
expressions are allowed. For example
the input of Mu=1 and Sigma=1 for the normal distribution gives the same result as
Mu=3*Math.pow(4,1/2)-5 and Sigma=2*Math.sin(Math.PI/2)-1 or Mu=3-2 and Sigma=-1+2*1.
|If you change the digits or parameters you have to click into the x- (or F(x)-) field before pressing the "x->F(x)"-
(Source: Numerical Recipes in Pascal). The books of Johnson+Kotz (Continuous
Distributions I+II, Discrete Distributions) were also used.
