ChiSquaredDistribution

Constructors

constructor(degreesOfFreedom: Double, name: String? = null)

open override fun cdf(x: Double): Double

Returns the F(x) = Pr{X <= x} where F represents the cumulative distribution function

open override fun domain(): Interval

open override fun invCDF(p: Double): Double

Provides the inverse cumulative distribution function for the distribution

open override fun mean(): Double

Returns the mean or expected value of a distribution

open override fun parameters(): DoubleArray

Gets the parameters

open override fun parameters(params: DoubleArray)

Sets the parameters

open override fun pdf(x: Double): Double

Returns the f(x) where f represents the probability density function for the distribution. Note this is not a probability.

open override fun randomVariable(streamNumber: Int, streamProvider: RNStreamProviderIfc): ChiSquaredRV

Promises to return a random variable that uses the supplied stream number using the supplied stream provider

open override fun toString(): String

open override fun variance(): Double

Returns the variance of the distribution if defined
