CDF(Double) |
Returns the cumulated distribution function for value x with the distribution parameters numf and denomf.
(Overrides ProbabilityDistributionCDF(Double)) | |
CDF(Double, Double, Double) | Returns the cumulated distribution function for value x with the distribution parameters numf and denomf. | |
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) | |
NextDouble | (Overrides ProbabilityDistributionNextDouble) | |
PDF(Double) |
Returns the probability density function for value x with the distribution parameters p and q.
(Overrides ProbabilityDistributionPDF(Double)) | |
PDF(Double, Double, Double) | Returns the probability density function for value x with the distribution parameters p and q. | |
Quantile(Double) |
Quantile of the F-distribution.
(Overrides ProbabilityDistributionQuantile(Double)) | |

DF | ||
generator | Pointer to generator. (Inherited from ProbabilityDistribution) | |
NF | ||
NumChi2 |
Return F-distributed (variance ratio distributed) random deviates
with n numerator degrees of freedom and d denominator degrees of freedom
according to the density:
p (x) dx = ... dx
n,d
Both paramters n and d must be positive.
Method: The random numbers are directly generated from ratios of
ChiSquare variates according to:
F = (ChiSquare(n)/n) / (ChiSquare(d)/d)
