Improved Nonparametric Control Chart Based on Ranked Set Sampling with Application of Chemical Data Modelling
نویسندگان
چکیده
The statistical performance of parametric control charts is questionable when the underlying process does not follow any specified probability distribution. Nonparametric are best substitute for this situation. On other hand, ranked set sampling technique preferred over simple random because it reduces variability parameters and improves chart’s performance. This study aims to offer a nonparametric double homogeneously weighted moving average chart under Wilcoxon signed-rank test considering (regarded as NPDHWMA RSS ), further enhance location monitoring. proposed run-length compared with competing charts, such DEWMA- id="M2"> X ¯ , NPDEWMA-SR, NPRDEWMA-SR, DHWMA, id="M3"> NPHWMA charts. comparison revealed that id="M4"> outperformed particularly small moderate shifts in location. Finally, real-life application also offered quality practitioners show strength chart.

Bayesian nonparametric models for ranked set sampling.
Ranked set sampling (RSS) is a data collection technique that combines measurement with judgment ranking for statistical inference. This paper lays out a formal and natural Bayesian framework for RSS that is analogous to its frequentist justification, and that does not require the assumption of perfect ranking or use of any imperfect ranking models. Prior beliefs about the judgment order statis...
متن کاملImproved Estimation from Ranked Set Sampling
Ranked set sampling is used when the measurement or quantification of units of the variable under study is difficult but the ranking of units of sets of small sizes can be done easily by an inexpensive method. Dell and Clutter (1972) showed that the sample mean based on ranked set sample is more efficient than the sample mean based on simple random sample with replacement sampling procedure for...
متن کاملEstimation of Variance of Normal Distribution using Ranked Set Sampling
Introduction In some biological, environmental or ecological studies, there are situations in which obtaining exact measurements of sample units are much harder than ranking them in a set of small size without referring to their precise values. In these situations, ranked set sampling (RSS), proposed by McIntyre (1952), can be regarded as an alternative to the usual simple random sampling ...
متن کاملQuantile Estimation from Ranked Set Sampling Data
We consider estimation of quantiles when data are generated from ranked set sampling. A new estimator is proposed and is shown to have a smaller asymptotic variance for all distributions. It is also shown that the optimal sampling strategy is to select observations with one fixed rank from different ranked sets. Both the optimal rank and the relative efficiency gain with respect to simple rando...
متن کاملAdaptive Nonparametric CUSUM Control Chart with Variable Sampling Interval Strategy
In this paper, we propose a nonparametric CUSUM control chart for detecting a range of shifts in the location parameters based on previous research. This control chart is dynamically adaptive, ranks method-based nonparametric and self-starting; it can monitor various sizes of shifts in difference distributions simultaneously; and it can be used to monitor processes at the start-up stages. This ...
