- Field Detail
  - ALPHA_THRESHOLD_ID
```
public static final OptionID ALPHA_THRESHOLD_ID
```
    Parameter for the chi squared test threshold.
  - POISSON_THRESHOLD_ID
```
public static final OptionID POISSON_THRESHOLD_ID
```
    Parameter for the poisson test threshold.
  - MAX_EM_ITERATIONS_ID
```
public static final OptionID MAX_EM_ITERATIONS_ID
```
    Maximum number of iterations for the EM step.
  - EM_DELTA_ID
```
public static final OptionID EM_DELTA_ID
```
    Threshold when to stop EM iterations.
  - MIN_CLUSTER_SIZE_ID
```
public static final OptionID MIN_CLUSTER_SIZE_ID
```
    Minimum cluster size for noise flagging. (Not existant in the original publication).
  - alpha
```
protected double alpha
```
    Parameter for the chi squared test threshold. While statistical values such as 0.01 are a good choice, we found the need to modify this parameter in our experiments.
  - poissonThreshold
```
protected double poissonThreshold
```
    Parameter for the poisson test threshold.
  - maxEmIterations
```
protected int maxEmIterations
```
    Maximum number of iterations for the EM step.
  - emDelta
```
protected double emDelta
```
    Threshold when to stop EM iterations.
  - minClusterSize
```
protected int minClusterSize
```
    Minimum cluster size for noise flagging. (Not existant in the original publication).

- Method Detail
  - configure
```
public void configure(Parameterization config)
```
    Description copied from interface: Parameterizer
    
    Configure the class.
    Note: the status is collected by the parameterization object, so that multiple errors may arise and be reported in one run.
    
    Specified by:
    
    configure in interface Parameterizer
    
    Parameters:
    
    config - Parameterization
  - make
```
public P3C make()
```
    Description copied from interface: Parameterizer
    
    Make an instance after successful configuration.
    Note: your class should return the exact type, only this very broad interface should use Object as return type.
    
    Specified by:
    
    make in interface Parameterizer
    
    Returns:
    
    a new instance
