{"doi":"10.13005/ojps08.01.06","title":"On Modification of Some Ratio Estimators using Parameters of Auxiliary Variable for the Estimation of the Population Mean","abstract":"<jats:p>Some existing estimators based on auxiliary attribute have been proposed by many authors. In this paper, we use the concept of power transformation to modify some existing estimators in order to obtain estimators that are applicable when there is positive or negative correlation between the study and auxiliary variable. The properties (Biases and MSEs) of the proposed estimators were derived up to the first order of approximation using Taylor series approach. The efficiency comparison of the proposed estimators over some existing estimators considered in the study were established. The empirical studies were conducted using existing population parameters to investigate the proficiency of the proposed estimators over some existing estimators. The results revealed that the proposed estimators have minimum Mean Square Errors and higher Percentage Relative Efficiencies than the conventional and other competing estimators in the study. These implies that the proposed estimators are more efficient and can produce better estimates of the population mean compared to the existing estimators considered in the study.</jats:p>","journal":"Oriental Journal of Physical Sciences","year":2023,"id":39388,"datarank":0.17646086704861919,"base_score":0.6931471805599453,"endowment":0.6931471805599453,"self_citation_contribution":0.10397207708399181,"citation_network_contribution":0.07248878996462736,"self_endowment_contribution":0.10397207708399181,"citer_contribution":0.07248878996462736,"corpus_percentile":null,"corpus_rank":null,"citation_count":1,"citer_count":1,"citers_with_citation_signal":1,"citers_with_endowment":1,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":null,"is_data_producer":false,"deposit_databanks":null,"is_oa":false,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":null,"fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":193540,"name":"Wasiu Afolabi Babayemi","orcid":null,"position":1,"is_corresponding":false},{"id":193541,"name":"Ahmed Audu","orcid":null,"position":2,"is_corresponding":false},{"id":193542,"name":"Awwal Adejumobi","orcid":null,"position":3,"is_corresponding":false},{"id":193539,"name":"Gerald Ikechukwu Onwuka","orcid":null,"position":0,"is_corresponding":false}],"reference_count":0,"raw_metadata":{"has_enrichment":true,"base_score":0.6931471805599453,"endowment":0.6931471805599453,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"18998881","pmcid":null,"openalex_id":"https://openalex.org/W4385769873","authors":[],"funders":[],"total_grants":0,"fwci":0.3157,"citation_percentile":0.61842855,"influential_citations":0,"citation_trend":[{"year":2025,"count":1}],"oa_status":"gold","license":"cc-by","oa_locations":[{"url":"https://www.orientaljphysicalsciences.org/pdf/vol8no1/OJPS_Vol8_No1_p_27-35.pdf","host_type":"journal"},{"url":"https://www.orientaljphysicalsciences.org/pdf/vol8no1/OJPS_Vol8_No1_p_27-35.pdf","host_type":"GOLD"},{"url":"https://www.orientaljphysicalsciences.org/pdf/vol8no1/OJPS_Vol8_No1_p_27-35.pdf","host_type":"publisher"},{"url":"https://www.orientaljphysicalsciences.org/vol8no1/on-modification-of-some-ratio-estimators-using-parameters-of-auxiliary-variable-for-the-estimation-of-the-population-mean/","host_type":"publisher"},{"url":"https://doi.org/10.13005/ojps08.01.06","host_type":"journal"}],"fields_of_study":["Survey Sampling and Estimation Techniques","Statistical Methods and Bayesian Inference","Mathematics"],"mesh_terms":[],"keywords":["Estimator","Extremum estimator","Mathematics","M-estimator","Mean squared error","Population","Variable (mathematics)","Statistics","Efficiency","Transformation (genetics)","Econometrics"],"sdg_mappings":[],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-06-11T19:48:37.208880Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
