Constructor Details

GaussianIATimeRV

public GaussianIATimeRV(double mean,
 double sdev)

Constructor.

Parameters:

mean - the mean value of this random variable

sdev - the standard deviation of this random variable

Method Details

getMean

public double getMean()

Get the mean value for the random-variable.

Returns:

the mean value

getSDev

public double getSDev()

Get the standard deviation for the random variable.

Returns:

the standard deviation

next

public Long next()

Get the next value.

Specified by:

next in interface RandomVariableOps<Long>

Specified by:

next in class RandomVariable<Long>

Returns:

the next value, rounded to the nearest long integer

next

public double next(int n)

Get the sum of multiple values with the number of values an int. The range check, if any, is applied to the result, not the individual random values that were summed. The implementation is more efficient than one that calls next() n times.

Parameters:

n - the number of values to use

Returns:

the sum of n values of this random variable

next

public Long next(long n)

Get the sum of multiple values with the number of values a long. The range check, if any, is applied to the result, not the individual random values that were summed. The implementation is more efficient than one that calls next() n times.

Parameters:

n - the number of values to use

Returns:

the sum of n values of this random variable

toString

public String toString()

Overrides:

toString in class Object
