```
public double[] guess(Collection<WeightedObservedPoint> observations)
```
    Computes an estimation of the parameters.
    Specified by:
    
    guess in class SimpleCurveFitter.ParameterGuesser
    
    Parameters:
    
    observations - Observations.
    
    Returns:
    
    the guessed parameters, in the following order:
    
    Normalization factor
    
    Mean
    
    Standard deviation
    
    Throws:
    
    NullArgumentException - if observations is null.
    
    NumberIsTooSmallException - if there are less than 3 observations.
