Kappa
katsayısı iki değerlendiricinin sınıflandırmaları arasındaki uyumu ölçen
popüler bir istatistiktir. Kappa katsayısı ve varyansının tahmini yaklaşık
olarak basit rasgele örnekleme yöntemiyle elde edilir. Kappa istatistiğinin
güven aralığı tahmininde daha etkin sonuçlar elde edebilmek için tabakalı rasgele
örnekleme yöntemi de kullanılabilir. Bu çalışmada, kappa katsayısının güven
aralığı tahmin etmek için tabakalı rasgele örneklem seçimi altında bir
bootstrap yöntemi önerilmiştir. Sonuçlar üç veri kümesi üzerinden
tartışılmıştır.

Kappa coefficient is a popular statistic to measure
the agreement between the classifications of two raters. The estimator of the coefficient
and its variance are approximately satisfied by a simple random sampling method.
To get more efficient results for confidence interval estimation of kappa,
stratified random sampling method can also be used, alternatively. In this
study, a bootstrap method under stratified sampling is suggested to use to
estimate the confidence interval of kappa coefficient. The results are
discussed over three data sets.
