PowerFunctionDistribution()
Default constructor: creates a Power-Function distribution with scale and shape
parameters equal to 1
|
PowerFunctionDistribution(double[] distData) |
PowerFunctionDistribution(double a,

PowerFunctionDistribution(float[] distData) |
Modifier and Type | Method and Description |
---|---|
double |
getCDF(double x)
Compute the cumulative distribution function.
|
double |
getDensity(double x)
Define the PowerFunction getDensity function
|
double |
getMaxDensity()
Compute the maximum getDensity
|
double |
getMean()
Compute the mean in closed form
|
double |
getMode()
Compute the Mode in closed form
|
java.lang.String |
getOnlineDescription()
This method returns an online description of this distribution.
|
double |
getScale()
Get the scale paramter
|
double |
getSD()
Compute the variance in closed form
|
double |
getShape()
Get the shape parameter
|
double |
getVariance()
Compute the variance in closed form
|
void |
initialize()
used for some subclass to initialize before being used
|
void |
paramEstimate(double[] distData)
overwrites the method in distribution for estimating parameters
By assuming that the shape parameter is known, the location and scale parameters could
be easily obtained by using the maximum likelihood estimation method.
|
void |
setParameters(double a,
double b)
Set the parameters, compute the normalizing constant NormalizingConst, and specifies the
interval and partition
|
void |
setScale(double b)
Sets the Scale parameter
|
void |
setShape(double a)
Sets the Shape parameter
|
