We evaluate the statistical visibility of information hiding algorithms based on the coefficient of kurtosis, differential entropy, goodness of fit test and kullback entropy. on these bases some methodologies are suggested to defend against statistical steganalysis
重點研究了含密序列統計可見性的定量評估，提出了基於峰度系數和微分墑的偏態評估、基於擬和優度檢驗的統計可見性評估和基於鑒別信息的統計可見性評估。 -
The resuts showed that the annual average temperature had an increasing trend ; summer, autumn and winter average temperature also had an increasing trend and the amplitude in winter was bigger ; the change of standard deviation and coefficient of variation were acute during winter ; the coefficients was bigger ; the change of standard deviation and coefficient of variation were acute during winter ; the coefficients of skewness were positive value during summer and autumn ; the kurtosis coefficients were bigger during winter
得出如下結論：和田地區年氣溫有增加的趨勢；夏季、秋季、冬季氣溫也有增加的趨勢且冬季氣溫值增幅較大；標準差及變差系數都是冬季變化較為劇烈；偏度系數在夏季及秋季為正值；峰度系數值在冬季較大。 -
Secondly, we construct the sequential confidence intervals for the common number characters : coefficient of variation, skewness and kurtosis, stressing on computing their asymptotic variances in their limiting distributions
其次，我們就常用的數字特徵變異系數、偏度和峰度分別建立了它們的序貫置信區間程序，著重算出它們極限分佈中的相關漸近方差。
