Abstract

Aktivitas kehidupan banyak peristiwa yang berhubung dengan waktu kelangsungan hidup, misal durasi waktu yang dibutuhkan untuk sembuh dari penyakit. Lama waktu yang dibutuhkan hingga terjadinya suatu peristiwa tertentu itulah yang disebut waktu survival. Pada umumnya data waktu survival tidak sepenuhnya dapat diamati atau disebut dengan data tersensor. Salah satu metode statistika yang dapat digunakan dalam menganalisis data survival, adalah model cox proportional hazard. Penelitian ini bertujuan untuk mengetahui tingkat kelangsungan hidup penderita HIV/AIDS, digunakan fungsi hazard dan fungsi survival dengan variabel lama rawat inap pasien sebagai respon. Untuk mengetahui faktor-faktor lain yang mempengaruhi ketahan hidup penderita HIV/AIDS digunakan model cox proportional hazard. Hasil penelitian menunjukkan bahwa Hasil Estimasi fungsi survival Kaplan Meier dan fungsi hazard kumulatif Nelson Aalen menunjukan bahwa semakin lama pasien menderita HIV/AIDS maka probabilitas survival pasien semakin kecil, namun resiko kematian disebabkan HIV/AIDS semakin tinggi. Tingkat pendidikan, status pekerjaan, status fungsional, Kadar CD4 merupakan faktor yang berpengaruh dalam resiko kematian pasien HIV/AIDS

Abstract

This study aims to model the factors that affect the financial performance of Bank Muammalat, including Capital Adequacy Ratio (CAR), Earning Asset Quality (KAP), Operational Expenses to Operating Income (BOPO), and Financing to Deposit Ratio (FDR) to Return on Assets. (ROA) This research uses secondary data taken based on time series. The analysis technique in this study uses multiple linear regression using SPSS software version 20 and Microsoft Office Excel 2010. The results of this study indicate that partially the CAR and KAP partially do not have a significant effect on Return On. Assets, while Operational Expenses to BOPO and FDR partially have a significant effect on Return on Assets. Simultaneously, these four variables have a significant effect on Return on Assets at PT Bank Muamalat Indonesia. Based on the results of the Determination Coefficient test, the value of Adjusted R Square (R2) is 99.00%, this means that the amount of Return on Assets can be influenced and explained by the variables CAR, KAP, BOPO, and FDR, while the remaining 1% is explained by variables not examined in this study.

Abstract

Regression is a data analysis method used to model the relationship between one response variable and one or more predictor variables. In regression modelling, data is often used. In general, the regression model that is often used is simple or multiple regression in modelling where the response variable is quantitative data. The fundamental difference from regression models using quantitative data is the main objective is to estimate the average value of the dependent variable using certain values of the independent variable. Whereas in a regression model with a qualitative dependent variable the main objective is to find the probability of something happening (probability model). One of the development methods of the regression model for data with qualitative response variables is Logistic and Probit regression. The purpose of this study was to compare the best model using binary logistic regression with binary probit regression in the case of Labor Force Participation Rate (TPAK) in Gorontalo City. The research method used is quantitative research methods, with binary logistic regression modelling and binary probit regression. The results showed that the variable that has a significant effect on TPAK Gorontalo City is the open unemployment rate, and the best model between the binary logistic regression model with an AIC value of 1.289 is smaller than the AIC value of the binary Probit regression 1.318, likewise from the R2 value the R2 value for regression is obtained. binary logistic of 12.74%, greater than the R2 value of binary probit regression of 10.70%.

Abstract

ABSTRAKPertumbuhan ekonomi merupakan indikator yang digunakan untuk mengetahui kualitas hidup dan kemakmuran suatu wilayah demikan halnya juga dengan kemiskinan yang menjadi indikator dalam mengukur kesejahteraan masyarakat. Dalam pemodelan dampak pertumbuhan ekonomi terhadap penurunan angka kemiskinan digunakan salah satu model ekonometrika yaitu system persamaan simultan. Dalam penelitian ini dilakukan pemodelan menggunakan model simultan antara pertumbuhan ekonomi dan kemiskinan. Estimasi parameter yang digunakan adalah Two-Stage Least Square Estimation (2SLS). Data yang dignakan adalah data mengenai pertumbuhan ekonomi di Indonesia. Hasil analisis menunjukkan bahwa inflasi dan kemiskinan berpengaruh signifikan terhadap pertumbuhan ekonomi, sementara itu investasi, angka harapan hidup, angka melek huruf, dan lama pendidikan berpengaruh signifikan terhadap kemiskinan.Kata kunci: Persamaan Simultan, Pertumbuhan Ekonomi, KemiskinanABSTRACTEconomic growth is an indicator used to determine the quality of life and prosperity of an area as well as poverty which is an indicator in measuring the welfare of society. In modeling the impact of economic growth on poverty reduction, an econometric model is used, namely a system of simultaneous equations. In this study, modeling was carried out using a simultaneous model between economic growth and poverty. The parameter estimation used is Two-Stage Least Square Estimation (2SLS). The data used is data on economic growth in Indonesia in 2000 - 2018.The results of the analysis show that inflation and poverty have a significant effect on economic growth, meanwhile investment, life expectancy, literacy, and length of education have a significant effect on poverty.

Abstract

Dalam menggunakan model regresi linier disyaratkan data yang digunakan hendaknya berskala interval atau rasio. Akan tetapi jika skala dalam bentuk ordinal tetap dipaksakan menggunakan model regresi linier, maka akan diperoleh koefisien korelasi yang kecil dan tidak memenuhi syarat sebagaimana yang diharapakan dalam model regresi. Tujuan dari penelitian ini adalah melihat bagaimana melakukan pemodelan regresi linier berganda dengan menggunakan data berskala ordinal yang ditransformasi menjadi data interval. Data yang digunakan adalah data mengenai tingkat kepatuhan pembayaran pajak di Provinsi Gorontalo. Data hasil penelitian ini berskala ordinal sehingga dilakukan transformasi data menjadi skala interval dengan menggunakan metode suksesif interval. Setelah dilakukan transformasi, diperoleh model regresi dengan menggunakan data interval maka asumsi model regresi linier berganda terpenuhi, dan mempunyai kooefisien determinasi yang lebih tinggi, sedangkan model regresi linier dengan menggunakan data ordinal maka asumsi regresi linier tidak terpenuhi.
