Based on remote sensing and GIS technology,the images of remote sensing from 1980 to 2007 were used to the basis of the data source,to obtain different information about Changsha urban landscape change,the dynamic landscape analysis was applied by the transfer matrix method and Kappa index of Changsha.

The Kappa shape index and connectivity index was obtained.

Based on remote sensing images and geographic information system,and by using landscape metrics and Kappa coefficient,this paper studied the farmland landscape change in Wenchuan County of Minjiang River upper reach.

Measuring spatial information changes using Kappa coefficients: a case study of the city groups in central Liaoning Province;

14% and Kappa coefficient is 0.

The article sets forth that standard errors are different sometimes between confidence limits and hypothesis test in the light of examples of kappa coefficient and difference of two population rates.

Classified-model soft sensing method for Kappa number of pulp based on wavelet transform;

Soft Sensing Method of Kappa Number During Batch Cooking Process Based on Qualitative Knowledge and Linear PLS;

Study of the On--Line Pulp Kappa Number Soft-Sensing Technique During Bamboo Batch Kraft Pulping;

Then the results were analysed with Kappa statistics.

METHODS: 100 extracted human maxillary first molars were determined by two observers to locate the second mesiobuccal canals independently at 2 times, the interval was 2 weeks, then analysed the RESULTS with Kappa statistics.
