Constructor and Description |
---|
TriangleDistribution()
This default constructor creates a new triangle distribution on the
interval (0, 1) with positive slope
|
TriangleDistribution(double a,
double b,
int i)
This general constructor creates a new triangle distribution on a
specified interval and with a specified orientation.
|

getCDF(double x)
This method computes the cumulative distribution function.
|
double |
getDensity(double x)
The getDensity method is abstract and must be overridden for any specific
distribuiton

double |
getMean()
This method computes the mean.
|
double |
getMinValue()
This method returns the minimum value.
|
java.lang.String |
getOnlineDescription()
This method returns an online description of this distribution.
|
int |
getOrientation()
This method returns the orientation.
|
double |
getVariance()
This method computes the variance.

initialize()
used for some subclass to initialize before being used
|
void |
setParameters(double a,
double b,
int i)
This method sets the parameters: the minimum value, maximum value, and
orientation.
