Moments, order statistics and reliability measure for this distribution are derived. Data from anew distribution are generated. Then the methods of maximum likelihood estimators of the parameters are examined. Furthermore, testing goodness of fit for the distribution is discussed by two tests kolmogorov-smirnov test and Chi-square test Issued also as CD Beta modified The generalized beta modified weibull (GBMW) Weibull distribution Mahmoud Riad Mahmoud , Supervisor http://172.23.153.220/th.pdf Nazla Revisor Shimaa Cataloger ddc TH 61087 61087 ddc 0 CUCL cl210 2024-02-11 Cai01.18.03.M.Sc.2016.En.O 01010110070984000 2023-09-22 00:00:00 TH ddc 0 CUCL cl2u8 2024-02-11 Cai01.18.03.M.Sc.2016.En.O 01020110070984000 2023-09-22 00:00:00 70984.CD CD
