Modified Ratio-Type Estimators of the Mean using Extreme Ranked Set Sampling

Abstract

Abstract:Modified ratio-type estimators of the population mean were suggested using the first or third quartiles of the auxiliary variable based on Simple Random Sampling (SRS) and Extreme Ranked Set Sampling (ERSS) methods. It was found that, the ERSS was more efficient than the SRS based on the same sample size. Also, the ERSS involving the first quartile was superior to the third quartile.

Proposal of a Standardized Electronic Health Record for Kingdom of Saudi Arabia

“…Health Record (EHR) system US3: I found it easy to share information about the patient condition, get feedback about the patient history using proposed Electronic Health Record (EHR) system US4: I can accomplish the task quickly using this procedure US5: I believe that from using Proposed Electronic Health Record (EHR) system will reduce errors and save time ST.DEV Proposed Electronic Health Record (EHR) system will be improve 4.5 0.73 quality of care through greater access to information and history of the patient The interaction with Propose Electronic Health Record (EHR) system 4.1 0.92 would be clear and understandable I believe that from using proposed electronic health record system 3.9 0.78 will reduce errors and save time Sampling Technique: Sampling is a procedure that entails utilizing a small number of units in a given population as a basis for drawing conclusions regarding the whole population (Jemain et al, 2007). The sample is considered as a subset of the population comprising of some members selected from it (Al-Omari and Jaber, 2008). We aim to be able to draw generalized conclusions based on the population under study.…”

Weibull-Bayesian Estimation Based on Maximum Ranked Set Sampling with Unequal Samples

“…Shaibu and Muttlak [4] used median and extreme ranked set sampling method for estimating the parameters of normal, exponential and gamma distributions. Al-Omari et al [5] Used extreme ranked set sampling method to find the estimates of the population mean. Islam et al [6] Obtained the modified maximum likelihood estimator of location and scale parameters depend on selected ranked set sampling for normal distribution.…”
