 | SimpleRandomSampling Class |
Provides methods to randomly select samples from a finite population
where all samples of a given size share the same probability
to be selected.

SyntaxThe SimpleRandomSampling type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | SimpleRandomSampling |
Initializes a new instance of
the SimpleRandomSampling class.
|
Properties| Name | Description | |
|---|---|---|
 | InclusionProbabilities |
Gets the inclusion probabilities of the
population units.
(Overrides RandomSamplingInclusionProbabilities.) |
| PopulationSize |
Gets the size of the population from which this
instance draws samples.
(Overrides RandomSamplingPopulationSize.) |
| RandomNumberGenerator |
Gets or sets the basic random generator for this instance.
(Inherited from RandomDevice.) |
| SampleSize |
Gets the size of the samples drawn by this
instance.
(Overrides RandomSamplingSampleSize.) |
Methods| Name | Description | |
|---|---|---|
| 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.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| NextDoubleMatrix |
Draws a random sample represented as a DoubleMatrix
instance.
(Overrides RandomSamplingNextDoubleMatrix.) |
| NextIndexCollection |
Draws a sample represented as an IndexCollection
instance.
(Overrides RandomSamplingNextIndexCollection.) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
RemarksThe current implementation of the SimpleRandomSampling class is based on the Donald E. Knuth's Algorithm S (Selection sampling technique, p. 142)[1] .
