There is some investigation of the results of using such charts when a non-exponential Weibull distribution would be more appropriate. The paper concludes with a discussion of certain formulas in the related analysis of sequential probability ratio tests for Weibull distributions....
The fit of the Zipf–PSS is compared with those achieved by the negative binomial (NB) and the discrete Weibull (DW) (Nakagawa and Osaki, 1975) distributions. The models are compared by means of the Akaïke Information Criterion (AIC). The rest of the article is organized as follows. ...
Some characters of diameter distribution of Eucommia uimoides plantations were studied using indexes of SK (skewness) and ST(steepness) and the diameter distributions were simulated by the Weibull function and the Logistic function. :以偏度、峭度为指标研究了杜仲林分直径分布特征 ,分别采用韦布尔函数和...
Whereas it is well known that preventive replacements of units are effective only when their life time distributions have ξ >1, the precise estimation of ξ is practically very important. Therefore, in order to improve the precisions of the Weibull parameters estimations, there have been ...
This paper is concerned with the problem of obtaining the maximum likelihood prediction (point and interval) and Bayesian prediction (point and interval) for a future observation from mixture of two exponentiated Weibull (MTEW) distributions based on generalized order statistics (GOS). We consider ...
The exponentiated exponential distribution has received great attention from many statisticians due to its popularity, many applications, and the fact that it is an efficient alternative to many famous distributions such as Weibull and gamma distributions. Many statisticians have studied the mathematical ...
