For this type of data, this paper proposes a two-stage algorithm to estimate some commonly used lifetime distributions. This Mgorithm is automatic, intuitively appealing and simple to implement. Simulation studies show that compared with some existing methods, the proposed algorithm is more stable and efficient, especially in small sample situations, and it can also be extended to deM with some complicated lifetime distributions.展开更多

文摘Quantum statistical properties of the binomial field interacting with the two entangled atoms are investi-gated for the different initial conditions.It is found that the sub-Poissonian distribution and the antibunching effect canbe presented for the certain ranges of the involved parameters.
文摘By suitably choosing the normalization factors we introduce the even- and odd-negative binomial states. In some limit cases they approach the even- and odd-coherent states, respectively. We also derive a new eigenvector equation that the negative binomial state satishes as a nonlinear coherent state.
