在传播因子R-0位于确定性阈值1附近的过渡区域的复杂情况下，推导出随机Logistic流行病的准平稳分布的近似。在相同的参数范围内，给出了从准平稳性到灭绝的期望时间的近似值。(C)1999 Elsevier Science Inc. All rights reserved.
An approximation is derived for the quasi-stationary distribution of the stochastic logistic epidemic in the intricate case where the transmission factor R-0 lies in the transition region near the deterministic threshold value 1. An approximation for the expected time to extinction from quasi-stationarity in the same parameter region is also given. (C) 1999 Elsevier Science Inc. All rights reserved.
