Filia, Tita Ajrinna (2019) Perbandingan Antara Zero Imputation Dan Maximum Likelihood Mean Subtitutionuntuk Menangani Missing Data Pada Person-Trait Estimation. Sarjana thesis, Universitas Brawijaya.
Abstract
Fokus penelitianini adalah untuk mengetahui keefektifan penggunaan metodeconstant imputation dan maximum likelihoodmeansubtitution dalam penanganan missing data. Penelitian ini merupakan penelitian kuantitatif yang memiliki test lenght 40 aitem dengan pilihan respon politomus. Person-trait estimation dilakukan dengan expected a posteriori (EAP) berdasarkan model GRM dan akan dikorelasikan menggunakan Pearson’s Product Moment.Hasil penelitian menunjukkan bahwa penggunaan metode imputasi lebih efektif digunakan bila persentase missing databesar. Selain itu, penggunaan ML mean substitution lebih efektif digunakan dibandingkan dengan penggunaan constant imputation.
English Abstract
This study aims to determine the effectiveness of the constant imputation and maximum likelihood mean substitution to overcome missing data in estimating person-trait. This research were carried 40 items in the format of the polytomous response. The person-trait estimation is done with the expected a posteriori (EAP) based on the GRM model and will be correlated using Pearson’s Product Moment. The result showed that the imputation method was more effectively used when the percentage of missing data was large. In addition, ML mean substitution was more effectively than constant imputation to overcome missing data in estimating person-trait.
