Abstract

Mixed Geographically Weigted Regression (MGWR) adalah pengembangan dari model regresi dimana terdapat parameter yang dihitung pada setiap lokasi pengamatan, sehingga setiap lokasi pengamatan mempunyai nilai parameter yang berbeda-beda, regresi yang demikian dinamakan Geographically Weighted Regression (GWR). Penaksir parameter untuk GWR ini menggunakan WLS, karena dalam GWR terdapat matriks pembobot yang dibutuhkan. Dengan MGWR akan menghasilkan penaksir parameter yang sebagian bersifat global dan sebagian lain bersifat lokal sesuai dengan lokasi pengamatan. Penaksir pada model MGWR dapat dilakukan dengan metode WLS. Selanjutnya diperlukan serangkaian prosedur untuk melakukan uji hipotesis terhadap parameter model yang dihasilkan. Uji hipotesis ini digunakan untuk kesesuaian model dan juga menentukan variabel bebas mana yang berpengaruh signifikan terhadap model.Dari hasil penelitian didapatkan model statistik uji dari model MGWR adalah statistik uji F dan uji t. Pada aplikasi GWR4 didapatkan bahwa dari ke tujuh variabel, ternyata kesehatan ibu dan kesehatan bayi yang signifikan mempengaruhi jumlah kematian bayi di Jawa Timur tahun 2012.Sehingga model yang didapatkan dari pengujian signifikansi model GWR pada data jumlah kematian bayi di Jawa Timur tahun 2012 menggunakan aplikasi GWR4 adalah:y=33,930030+465,611379X6−469,063181X7Selain menggunakan statistik uji F dan uji t, dapat juga digunakan metode lainnya pada pengujian model MGWR. Estimasi parameter juga dapat menggunakan metode selain WLS, serta data yang sesuai dengan kebutuhan peneliti.

Abstract

Typhoid fever is a disease caused by Salmonella typhi bacteria. It is attack the digestive tract. Typhoid fever caused by poor sanitation and personal hygiene is not good. According to the Basic Health Research in 2007 showed that the prevalence of typhoid fever in Indonesia of 1.6%. NAD Province is hight typhoid fever prevalence(2,96 %). Because Having traced the biggest contributor was derived from NAD. Therefore, theresearch conducted to find factors that influence the outbreak of typhoid fever in NAD. research using the CART Method. The results of the analysis indicate that the main factor causing typhoid fever was drinking water reservoirs. The other factors are waste water reservoirs, the physical quality of drinking water, a habit washing hands with soap before eating, the bowel, the dump, gender, socioeconomic status, habits of washing hands with soap after defecation and health education.

Abstract

Dalam analisis regresi linier berganda adanya satu atau lebih pengamatan pencilan (outlier) akan menimbulkan dilema bagi para peneliti. Keputusan untuk menghilangkan pencilan tersebut harus dilandasi alasan yang kuat, karena kadang-kadang pencilan dapat memberikan informasi penting yang diperlukan. Masalah outlier ini dapat diatasi dengan berbagai metode, diantaranya metode regresi ridge (ridge regression). Untuk mengetahui kekekaran regresi ridge perlu melihat nilai-nilai R2, PRESS, serta leverage (hii), untuk metode regresi ridge dengan berbagai nilai tetapan bias k yang dipilih.

Abstract

Constant Elasticity of Substitution (CES) production function is the intrinsic nonlinear regression models that are often used to estimate the data in an industry. Intrinsic nonlinear regression model is a kindof nonlinear regression that can not be linearized, so as to estimate the beta parameters nonlinear statistical model used was Nonlinear Least Squares (NLS) using a first order taylor series approach used in the GaussNewton iteration. One of the problems often encountered in the analysis of data is an outlier, the presence of outliers in the data analysis greatly influence the results of the analysis so it becomes less valid and the estimationbecome biased. One method that is resistant to outliers regression is a method of Nonlinear Least Trimmed Squares. This research aims to determine the characteristics of parameter CES production function whichcontains outlier. The result shows that parameter of the production function CES which contains outliers are bias, inconsistent. So the CES production function which does not contain outliers better than the are containsoutliers.

Abstract

Discriminant Analysis is a statistical analysis that can classify cases on independent variables into groups or categories of dependent variables. The main objective of this research is classify eight indicators of the National education standards (SNP) early childhood and classify the accreditation value of early childhood (PAUD) in Southeast Sulawesi Province. The method used in this study used discriminant analysis. Accreditation value factors used in this study include Standards for Child Development Achievement Levels (X1), Content Standards (X2), Process Standards (X3), Standards for Educators and Education Personnel (X4), Facilities and Infrastructure Standards (X5), Management Standards (X6), Financing Standards (X7) and Education Assessment Standards (X8). Based on the results of data analysis, 8 SNP Indicators qualify as a form of discriminant equation model and accreditation value obtained based on the calculations of the National accreditation organization (BAN) PAUD and Non Fromal Education (PNF) Southeast Sulawesi are classified as follows: there are divided into 3 classifications, namely Accreditation C is 91.7%, Accreditation B is 85.1%, and for Accreditation A is 100%. So, the accuracy of the classification is 87.5%.
