It is a knowledge discovery technique to analyze hidden pattern and information from the available database. Due to uncertainty, fuzzy-based data mining techniques have been incorporated for decision-making. Fuzzy based data mining techniques model incomplete information and relations effectively in situations where lack of reasoning is given. A new fuzzy data mining algorithm has been proposed that helps in decision-making under uncertain conditions. The demonstration of the algorithm has been supported by means of a case study for the selection of suitable careers after studies. In the case study, data of 60 students studying in 4 different universities, pursuing 3 different courses have been taken. The decision making for the preparatory classes such as, further studies (F-S) or for job-oriented (JO) or coaching has been done by using the proposed method. From the results, it is concluded that student studying in the university U2 pursuing course C2 will take preparatory classes for job oriented course.","PeriodicalId":200461,"journal":{"name":"Research in Statistics","volume":" 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135292679","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The properties of the suggested estimator up to first order approximation were obtained. Theoretical as well as empirical comparison of the suggested estimator with the traditional unbiased stratified random sampling estimator when measurement errors are correlated was carried out. It was detected that the suggested estimator is a biased estimator and that correlated measurement errors inflate mean squared error of the suggested estimator but have no effect on the bias of the suggested estimator. The suggested estimator also recorded high loss in efficiency due presence of correlated measurement error. The paper concluded that the suggested estimator is more efficient than usual unbiased estimator.","PeriodicalId":200461,"journal":{"name":"Research in Statistics","volume":"139 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135569971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
