java.lang.Object
- jhplot.stat.MomentsNorm

```
public class MomentsNorm
extends Object
```
Calculations of normalized reduced moments of a distribution. The normalised reduced moments are calculated as up to an orbitrary order n, where n is the oder of the moment. The factorial moments are defined as
F_1=1 (1st order),
F_2=/^2 (second order),
F_2=/N^3 (3rd order)
and so on. The general form is /^q. The code works only for integer random variables. Statistical errors are also evaluated. If they are set to 0, this means that there is no enough events for their calculation.

```
public MomentsNorm(int order)
```
    Initialization of the normalised factorial moments.
    
    Parameters:
    
    order - Max oder of the normalised factorial moment
- Method Detail
  - process
```
public void process(int n)
```
    Process current event for an integer random variable
    
    Parameters:
    
    n - input variable for the moment calculations
  - getValues
```
public double[] getValues()
```
    Get values of the normalised factorial moments (NFM).
    
    Returns:
    
    array with values of the NFM.
  - getErrors
```
public double[] getErrors()
```
    Get errors on the factorial moment calculations. Call first getValues() to process the errors correctly. If the call returns 0, this means there is no enough evens for the calculation.
    
    Returns:
    
    array with statistical errors
  - getResults
```
public P1D getResults()
```
    Get results in form of P1D.
    
    Returns:
    
    p1d with values and errors
  - doc
```
public void doc()
```
    Show online documentation.
