In fact, in different situations having the same asymptotic expectation and variance of the estimator, the density function may differ in a considerably way especially with respect to the skewness.Confidence intervals for the ratio of two means which keep in consideration the shape of the ...

Improved Classes of Estimators for Ratio of Two Means with Double Sampling the non Respondents In this paper, we have considered the problem of estimation of ratio of two population means (R) using multivariate auxiliary characters with known populat... BB Khare,RR Sinha - 《Statistika Statistics...
Methods for interval estimation and hypothesis testing about the ratio of two independent inverse Gaussian (IG) means based on the concept of generalized variable approach are proposed. As assessed by simulation, the coverage probabilities of the proposed approach are found to be very close to the ...

Five estimation approaches have been developed to compute the confidence interval (CI) for the ratio of two lognormal means: (1) T, the CI based on the t-test procedure; (2) ML, a traditional maximum likelihood-based approach; (3) BT, a bootstrap approach; (4) R, the signed log-li...
