Abstract: A general statement of the interval estimation problem of a
proportion of two ratios according to data from two independent samples is
considered. Each sample may be obtained in the framework of direct or inverse
binomial sampling. Four asymptotic confidence intervals are constructed in
accordance with different types of sampling schemes. The main probability
characteristics of the intervals are investigated by the Monte-Carlo method:
coverage probability, median, mean, and standard deviation of interval length.
The results of the simulations show that we can arrange the new confidence
intervals in descending order according to the size of the regions of values where
their application is recommended as follows: direct-direct, direct-inverse when
the asymptotic variance is used, direct-inverse when the number of successes in
