public class ContinuousUniformDistribution extends Distribution implements java.io.Serializable
CONTINUOUS, DISCRETE, MIXED
Constructor and Description |
---|
ContinuousUniformDistribution()
This default constructor creates a new uniform distribuiton on (0, 1).
|
ContinuousUniformDistribution(double a,
double b)
This general constructor creates a new uniform distribution on a specified interval.
|
Modifier and Type | Method and Description |
---|---|
double |
getCDF(double x)
This method computes the cumulative distribution function in terms of the parameters.
|
double |
getDensity(double x)
This method computes the probability density function.
|
double |
getLowerBound()
This method gets the lower bound of the domain of the distribution.
|
double |
getMaxDensity()
This method computes the maximum value of the density function, which is any
value, since the density function is constant.
|
double |
getMean()
This method computes the mean of the distribution in terms of the parameters.
|
double |
getMGF(double t)
This method computes the moment generating function in terms of the parameters.
|
double |
getMoment(double a,
int n)
'
This method computes the moment of a specified order about a specified point, in
terms of the parameters.
|
double |
getQuantile(double p)
This method computes the quantile function in terms of the parameters.
|
double |
getUpperBound()
This method returns the upper bound of the domain.
|
double |
getVariance()
This method computes the variance of the distribution in terms of the parameters.
|
void |
setLowerBound(double a)
This method sets the lower bound of the domain.
|
void |
setParameters(double a,
double b)
This method sets the parameters: the minimum and maximum values of the interval.
|
void |
setUpperBound(double b)
This method sets the upper bound of the domain.
|
java.lang.String |
toString()
This method returns a string that gives the name of the distribution and the values of
the parameters.
