Constructor Detail

MaximumCorrelationCoefficient

public MaximumCorrelationCoefficient()

Constructs a new instance of the performance measure MaximumCorrelationCoefficient.

MaximumCorrelationCoefficient

public MaximumCorrelationCoefficient(StringBuffer xml)
                              throws NonParsableException

The standard constructor for the interface Storable. Constructs a MaximumCorrelationCoefficient out of an XML representation.

Parameters:

xml - the XML representation as StringBuffer

Throws:

NonParsableException - if the MaximumCorrelationCoefficient could not be reconstructed out of the StringBuffer xml
