Constructor Detail

DistUniform

public DistUniform(StreamInterface stream,
                   double a,
                   double b)
constructs a new uniform distribution. a and b are real numbers with a less than b. a is a location parameter, b-a is a scale parameter.

Parameters:
stream - the numberstream
a - the minimum value
b - the maximum value
Method Detail

draw

public double draw()
Description copied from class: DistContinuous
draws the next stream value according to the probability of this this distribution.

Specified by:
draw in class DistContinuous
Returns:
the next double value drawn.
See Also:
DistContinuous.draw()

probDensity

public double probDensity(double observation)
Description copied from class: DistContinuous
returns the propbability density value of an observation

Specified by:
probDensity in class DistContinuous
Parameters:
observation - the observation.
Returns:
double the probability density.

#probDensity(double)

toString

public String toString()
Overrides:
toString in class Object
