## Constructors

- [DiscreteDistribution](https://developer.rhino3d.com/api/gh2/type/grasshopper2.types.random.discretedistribution/ctor.md)

## Properties

- [Deviation](https://developer.rhino3d.com/api/gh2/type/grasshopper2.types.random.discretedistribution/deviation.md): Gets the standard deviation of this distribution. Not all types of distribution have a meaningful deviation, in which case this property returns NaN.
- [Entropy](https://developer.rhino3d.com/api/gh2/type/grasshopper2.types.random.discretedistribution/entropy.md): Gets the entropy of this distribution. Not all types of distribution have an entropy value, in which case this property returns NaN.
- [Maximum](https://developer.rhino3d.com/api/gh2/type/grasshopper2.types.random.discretedistribution/maximum.md): Gets the largest parameter for which this distribution is defined.
- [Mean](https://developer.rhino3d.com/api/gh2/type/grasshopper2.types.random.discretedistribution/mean.md): Gets the mean of this distribution. Not all types of distribution have a mean, in which case this property returns NaN.
- [Median](https://developer.rhino3d.com/api/gh2/type/grasshopper2.types.random.discretedistribution/median.md): Gets the median of this distribution. Not all types of distribution have a median, in which case this property returns NaN.
- [Minimum](https://developer.rhino3d.com/api/gh2/type/grasshopper2.types.random.discretedistribution/minimum.md): Gets the smallest parameter for which this distribution is defined.
- [Mode](https://developer.rhino3d.com/api/gh2/type/grasshopper2.types.random.discretedistribution/mode.md): Gets the mode of this distribution. Not all types of distribution have a mode, in which case this property returns NaN.
- [Skewness](https://developer.rhino3d.com/api/gh2/type/grasshopper2.types.random.discretedistribution/skewness.md): Gets the statistical skewness of this distribution. Not all types of distribution have a skewness, in which case this property returns NaN.
- [Type](https://developer.rhino3d.com/api/gh2/type/grasshopper2.types.random.discretedistribution/type.md): Gets the type of this distribution.
- [Variance](https://developer.rhino3d.com/api/gh2/type/grasshopper2.types.random.discretedistribution/variance.md): Gets the statistical variance of this distribution. Not all types of distribution have a variance, in which case this property returns NaN.

- [CreateConwayMaxwell](https://developer.rhino3d.com/api/gh2/type/grasshopper2.types.random.discretedistribution/createconwaymaxwell.md): (static) Create a Conway-Maxwell-Poisson discrete distribution.
- [CreateGeometric](https://developer.rhino3d.com/api/gh2/type/grasshopper2.types.random.discretedistribution/creategeometric.md): (static) Create a Geometric discrete distribution.
