RandomVariableMutableClone (finmath lib 2.0.3 API)

All Implemented Interfaces:

Serializable, RandomVariableInterface

Deprecated.
```
public class RandomVariableMutableClone
extends Object
implements RandomVariableInterface
```
This class wraps an immutable class (here RandomVariableInterface) and implements the interface of an mutable class (here RandomVariableInterface). If a method is called which mutates the object (a mutator), a defensive copy is performed once. The reference to the immutable class is then replaced by the reference to the defensive copy. By returning an RandomVariableMutableClone of an RandomVariableInterface defensive copies are made only when necessary. This class is not thread safe (classes implementing RandomVariableInterface are not expected to be thread safe).

  - getHistogram
```
public double[] getHistogram(double[] intervalPoints)
```
    Deprecated.
    
    Description copied from interface: RandomVariableInterface
    Generates a Histogram based on the realizations stored in this random variable. The returned result array's length is intervalPoints.length+1.
    - The value result[0] equals the relative frequency of values observed in the interval ( -infinity, intervalPoints[0] ].
    - The value result[i] equals the relative frequency of values observed in the interval ( intervalPoints[i-1], intervalPoints[i] ].
    - The value result[n] equals the relative frequency of values observed in the interval ( intervalPoints[n-1], infinity ).
    where n = intervalPoints.length. Note that the intervals are open on the left, closed on the right, i.e., result[i] contains the number of elements x with intervalPoints[i-1] < x ≤ intervalPoints[i]. Thus, is you have a random variable which only takes values contained in the (sorted) array possibleValues, then result = getHistogram(possibleValues) returns an array where result[i] is the relative frequency of occurrence of possibleValues[i]. The sum of result[i] over all i is equal to 1, except for uninitialized random variables where all values are 0.
    Specified by:
    
    getHistogram in interface RandomVariableInterface
    
    Parameters:
    
    intervalPoints - Array of ascending values defining the interval boundaries.
    
    Returns:
    
    A histogram with respect to a provided interval.
  - getHistogram

                               double standardDeviations)
```
    Deprecated.
    
    Description copied from interface: RandomVariableInterface
    Generates a histogram based on the realizations stored in this random variable using interval points calculated from the arguments, see also RandomVariableInterface.getHistogram(double[]). The interval points are set with equal distance over an the interval of the specified standard deviation. The interval points used are x[i] = mean + alpha[i] * standardDeviations * sigma where
    - i = 0,..., numberOfPoints-1,
    - alpha[i] = (i - (numberOfPoints-1)/2.0) / ((numberOfPoints-1)/2.0),
    - mean = RandomVariableInterface.getAverage(),
    - sigma = RandomVariableInterface.getStandardDeviation().
    The methods result is an array of two vectors, where result[0] are the intervals center points ('anchor points') and result[1] contains the relative frequency for the interval. The 'anchor point' for the interval (-infinity, x[0]) is x[0] - 1/2 (x[1]-x[0]) and the 'anchor point' for the interval (x[n], infinity) is x[n] + 1/2 (x[n]-x[n-1]). Here n = numberOfPoints is the number of interval points.
    Specified by:
    
    getHistogram in interface RandomVariableInterface
    
    Parameters:
    
    numberOfPoints - The number of interval points.
