RSStest: An R Package for Hypothesis Test for Two Population Means with Ranked Set Sampling and Median Ranked Set Sampling

The hypothesis test for the equality of two population means of independent groups is the most commonly used statistical analysis with applications in medical sciences, agriculture, biology, engineering, social sciences and so on. This paper presents the RSStest package created to perform hypothesis testing for equality of two population means using ranked set sampling and median ranked set sampling. The package gives the test results such as test statistics, p value, critical values and basic comments. In addition, using this package, it is possible to select a sample from ranked set sampling and median ranked set sampling by ranking according to auxiliary variable from a given finite population. In addition, to demonstrate the use of these tests, a real data application on Copoeta trutta fish from Elazığ Keban Dam Lake was performed.
