AsymptoticKappaVariance ( GeneralConfusionMatrix matrix ) : double

Computes the asymptotic variance for Fleiss's Kappa variance using the formulae by (Fleiss et al, 1969) when the underlying Kappa is assumed different from zero.
AsymptoticKappaVariance ( GeneralConfusionMatrix matrix, double &stdDev, bool nullHypothesis = false ) : double

Computes the asymptotic variance for Fleiss's Kappa variance using the formulae by (Fleiss et al, 1969). If nullHypothesis is set to true, the method will return the variance under the null hypothesis.
AsymptoticKappaVariance ( WeightedConfusionMatrix matrix, double &stdDev, bool nullHypothesis = false ) : double

Computes the asymptotic variance for Fleiss's Kappa variance using the formulae by (Fleiss et al, 1969). If nullHypothesis is set to true, the method will return the variance under the null hypothesis.
DeltaMethodKappaVariance ( GeneralConfusionMatrix matrix ) : double

Compute Cohen's Kappa variance using the large sample approximation given by Congalton, which is common in the remote sensing literature.
DeltaMethodKappaVariance ( GeneralConfusionMatrix matrix, double &stdDev ) : double
