com.github.gwtd3.api.core.Random

public class Random
extends com.google.gwt.core.client.JavaScriptObject

A pseudorandom number generation function.

Random instances are created using static factory methods of this class, such as normal().

The generate() method is then used to generate numbers.

Method Detail

irwinHall

public static final Random irwinHall(int count)

Returns a function for generating random number with a Irwin-Hall distribution.

Parameters:

count - the number of independant variables

Returns:

the generator

normal

public static final Random normal()

Returns a function for generating random number with a normal (Gaussian) distribution, with a mean of 0 and a deviation of 1.

Returns:

the generator

normal

public static final Random normal(double mean)

Parameters:

mean - the mean

deviation - the deviation

Returns:

the generator

logNormal

public static final Random logNormal()

Returns a function for generating random number with a log-normal distribution, with a mean of 0 and a deviation of 1.

Returns:

the generator

logNormal

public static final Random logNormal(double mean)

Returns a function for generating random number with a log-normal distribution, with the given mean, and a deviation of 1.

The expected value of the generated pseudorandom numbers is mean, with the standard deviation of 1.

Parameters:

mean - the mean

Returns:

the generator

logNormal

public static final Random logNormal(double mean,
               double deviation)

Returns a function for generating random number with a log-normal distribution, with the given mean, and the given deviation.

Parameters:

mean - the mean

deviation - the deviation

Returns:

the generator

generate

public final double generate()
