“…Other robust estimation techniques are the M-regression, S-regression, and MM (modified maximum likelihood)-regression. Monte Carlo and empirical comparisons show that S-estimation (Singgih & Fauzan, 2022;Susanti, Pratiwi, Sulistijowati, & Liana, 2014) and the MM-method (Almetwally & Almongy, 2018) proved superior.…”

This note examines the impact of three institutional factors on environmental performance and carbon intensity of gross domestic product (GDP) for a cross-section sample of 154 countries. The institutional factors are democratization, market orientation of the economy, and prevalence of corruption. Per capita income is generally used as a control variable. As the distribution of some of the variables is highly skewed, we apply several robust regression methods, in comparison to ordinary least squares (OLS). Results differ depending on the estimation method, but generally per capita income is negatively related to carbon intensity but positively correlated with environmental performance. The higher the degree of democratization, the better the state of the environment and the lower the carbon intensity. Market orientation of the economy is ambiguous at first sight, but if an interaction variable with the democracy index is applied, the effect is quite large and highly significant. In this case, the impact of the corruption variable fades. Sensitivity analyses reveal, that introducing a democratic market economy is the most promising strategy to promote environmental performance as well as to cut the carbon emission intensity.

Corn is a food-crop commodity that has a strategic role in national development. Achievement of corn productivity is still relatively low. Under these conditions, the government has distributed assistance in the form of hybrid corn seeds of the BISI variety intending to increase productivity. This research was conducted in Nagreg District, Bandung Regency. This study aimed to analyze the effectiveness of the implementation of the hybrid corn seed assistance program and identify the necessary actions. This research employed a survey method. The research sample was taken using proportionate stratified random sampling on a sample of 73 farmers spread over 32 farmer groups. Data analysis used gap analysis to analyze the effectiveness of the program and Importance Performance Analysis (IPA) to identify the necessary actions. The results of the study indicated that the implementation of the hybrid corn seed assistance program has not been fully effective in increasing the productivity of corn farming. Suggestions for the government that further assistance programs to pay attention to the varieties of seeds distributed have proven productivity, to pay attention to the implementation schedule so that seed distribution can be on time, and to improve supervision in the field and apply strict sanctions for a delay in seed distribution.Â Jagung merupakan komoditas tanaman pangan yang memiliki peran strategis dalam pembangunan nasional. Pencapaian produktivitas jagung masih relatif rendah. Dengan kondisi tersebut pemerintah telah menyalurkan bantuan berupa benih jagung hibrida varietas BISI dengan tujuan meningkatkan produktivitas. Penelitian ini dilakukan di Kecamatan Nagreg Kabupaten Bandung. Penelitian ini bertujuan untuk menganalisis efektivitas pelaksanaan program bantuan benih jagung hibrida dan mengidentifikasi tindakan yang diperlukan. Penelitian ini menggunakan metode survey. Pengambilan sampel penelitian menggunakan proportionate stratified random sampling pada sampel sebanyak 73 petani yang tersebar di 32 kelompok tani. Analisis data menggunakan analisis gap untuk menganalisis efektivitas program dan Importance-Performance Analysis (IPA) untuk identifikasi tindakan yang diperlukan. Hasil dari penelitian menunjukkan bahwa pelaksanaan program bantuan benih jagung hibrida belum Â sepenuhnya efektif meningkatkan produktivitas usaha tani jagung. Saran bagi pemerintah agar program bantuan selanjutnya memperhatikan varietas benih yang disalurkan sudah teruji produktivitasnya, memperhatikan time schedule pelaksanaan sehingga penyaluran benih bisa tepat waktu, dan meningkatkan pengawasan di lapangan serta menerapkan sanksi yang tegas jika terjadi keterlambatan penyaluran benih.

“…Piradl et al (2021) considered the M-estimation for the linear regression model with correlated error terms and outliers. A comparison of M-estimation, S-estimation with MMestimation was proposed by Singgih and Fauzan (2022) to get the best estimation of robust regression in criminal cases in Indonesia.…”

Robust Estimation for Weibull Regression Model

2022

Weibull regression model is one of the most prevalently used parametric regression models. Estimation of the parameters of this model is affected by the presence of outliers. Outliers may be caused by actual rare events or by measurement, coding, or data entry errors, which cause a serious problem in parameter estimation. Therefore, robust estimation methods are used to overcome this problem since they are insensitive to perturbations. This paper discusses the efficiency of using two robust estimation methods, the M-estimation method and the MM-estimation method for estimating the parameters of Weibull regression model. Also, a Monte Carlo simulation study was conducted to compare the performance of robust M-estimation and MMestimation methods with the maximum likelihood method for estimating the parameters of Weibull regression model in the presence of outliers. The simulation results showed that the robust MMestimation method gives better performance than the maximum likelihood method and the M-estimation method.
