TY - JOUR PY - 2007// TI - Inferences on the common mean of several log-normal populations: the generalized variable approach JO - Biometrical journal A1 - Tian, Lili A1 - Wu, Jianrong SP - 944 EP - 951 VL - 49 IS - 6 N2 - This paper proposes a novel approach for the confidence interval estimation and hypothesis testing of the common mean of several log-normal populations using the concept of generalized variable. Simulation studies demonstrate that the proposed approach can provide confidence intervals with satisfying coverage probabilities and can perform hypothesis testing with satisfying type-I error control even at small sample sizes. Overall, it is superior to the large sample approach. The proposed method is illustrated using two examples.
