- com.singularsys.jep.functions.PostfixMathCommand
- - com.singularsys.jep.functions.NaryFunction
  - - com.singularsys.extensions.statistical.distributions.BinomialDist

All Implemented Interfaces:

PostfixMathCommandI, java.io.Serializable
```
public class BinomialDist
extends NaryFunction
```
The binomial distribution function. Works like Excel's BINOMDIST function. binomdist(x,n,p) gives the binomial distribution for x successes in n trial, with the probability of each trial being p. A four argument form binomdist(x,n,p,1) gives the cumulative distribution function.
