Estimating the ratio of means
Authors: ,
Abstract: Confidence intervals for ratio of means for large paired and unpaired samples with finite variance,obtained by applying the central limit theorem and Cramér-Wold device, are given. Also, these intervals for ratiosare obtained under infinite variance and when considering independent populations, by using stable distributions.Numerical illustrations by considering problems typically presented in practice are given.
