Rayleigh Class |
Continuous Univariate Rayleigh distribution.
The Rayleigh distribution (pronounced /ˈreɪli/) is a continuous probability distribution. As an
example of how it arises, the wind speed will have a Rayleigh distribution if the components of
the two-dimensional wind velocity vector are uncorrelated and normally distributed with equal variance.
For details about this distribution, see
Wikipedia - Rayleigh distribution.

Methods| Name | Description | |
|---|---|---|
 | CDF | Computes the cumulative distribution (CDF) of the distribution at x, i.e. P(X ≤ x). |
| CumulativeDistribution | Computes the cumulative distribution (CDF) of the distribution at x, i.e. P(X ≤ x). |

| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object) |
 | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object) |
| GetHashCode | Serves as the default hash function. (Inherited from Object) |
| GetType | Gets the Type of the current instance. (Inherited from Object) |
| InvCDF | Computes the inverse of the cumulative distribution function (InvCDF) for the distribution at the given probability. This is also known as the quantile or percent point function. |
