Jang Sik Cho (Korea), Kil Ho Cho (Korea) and Sang Gil Kang (Korea)
|
Abstract: In this paper, we consider two-components system for which the
lifetimes have bivariate Weibull model. We develop large sample tests for
testing independence between two-components and testing symmetry of
two-components. Also, we present simulated study which is the test based on
asymptotic normal distribution in both tests of independence as well as
symmetry. |
Keywords and phrases: bivariate Weibull model, independence, maximum likelihood estimator,
symmetry. |
