In this paper, we present the half logistic inverted Nadarajah–Haghigh (HL-INH) distribution, a novel extension of (INH) distribution. The probability density function (PDF) for HL-INH distribution might have unimodal, right skewness, or heavy-tailed shape numerous parameter values; however, forms hazard rate (HRF) may be decreasing. Four specific entropy measurements were investigated. Some us...

Ranked set sampling is applicable whenever ranking of a set of sampling units can be done easily by a judgement method or based on the measurement of an auxiliary variable on the units selected. In this work, we consider ranked set sampling, in which ranking of units are done based on measurements made on an easily and exactly measurable auxiliary variable X which is correlated with the study v...

We modify RSS to come up with new sampling method, namely, Multistage Median Ranked Set Sampling (MMRSS). The MMRSS was suggested for estimating the population median and to increase the efficiency of the estimator for specific value of the sample size. The MMRSS was compared to the Simple Random Sampling (SRS), Ranked Set Sampling (RSS) and Median Ranked Set Sampling (MRSS) methods. It is foun...
