Working on symmetrical or asymmetrical data is complicated since each requires a different probability density function. Many statistical distributions can be used for these types, where choosing one should satisfied with the correct type. So, we apply ranked set sampling technique, which essential in gaining when dealing units population expensive. However, their classification simple according to variable of interest. The Unit Generalized Rayleigh distribution has recently played crucial role analyzing complex sets specifically modeling claim and risk actuarial financial studies, its take symmetric asymmetric possible shapes. It proposed various areas, such as reliability, survival, economics, science, insurance. We applied design this article model parameter estimations unit generalized model. Different estimation procedures measures are computed. Moreover, performance illustrated via numerical simulation experiments. Under estimators, conduct validation suggested numerous Monte Carlo experiments by computing average bias mean squared errors. At end, two real applications area demonstrating potential supremacy estimators.

Abstract A very useful modification to ranked set sampling (RSS) that allows a larger size without significantly increasing ranking errors is the maximum with unequal samples (MRSSU) approach. This article covers parameter estimation of inverted Kumaraswamy distribution using MRSSU and RSS designs.

Based same number measured units, results real analysis showed estimators performed much better than their counterparts.

ABSTRACT Ranked set sampling (RSS) is an efficient method when ranking observations easier than precise measurement. Unlike simple random (SRS), RSS can reduce costs. The unit Xgamma distribution (UXGD), defined over the interval (0,1), effectively captures characteristics of negatively skewed datasets. This study aims to comprehensively compare several estimation methods, including maximum likelihood, Anderson‐Darling, Kolmogorov, ordinary least squares, Anderson‐Darling left tail second order, Cramer‐von‐Mises, weighted product spacing, right and five types minimum spacing distance for UXGD parameter under both SRS techniques. Through extensive simulations, we evaluate performance these estimators using multiple criteria designs. We rank based on their schemes. Simulation findings indicate that likelihood methods are superior alternative approaches assessing estimated quality SRS, respectively. It interesting note datasets, estimates revealed by our model satisfy consistency property. With increase in sample size, approach true values. Furthermore, results highlight efficiency gains as evidenced improved accuracy metrics. Two real‐world applications, COVID‐19 data from United Kingdom France, demonstrate practical utility findings.
