GEOGRAPHICALLY WEIGHTED BIVARIATE ZERO INFLATED POISSON REGRESSION (GWBZIPR) MODELLING WITH ADAPTIVE GAUSSIAN KERNEL WEIGHT FUNCTION

Siti Masliyah Lubis., Henny Pramoedyo., and Suci Astutik

Abstract:

Bivariate Poisson regression is a method used to model a pair of data counts with a Poisson distribution that has a correlation. This model has specific assumptions, namely similarities between averages and variance (equilibrium). Violations of this assumption cause the parameters produced from bivariate Poisson regression to be less accurate. Violations of these assumptions can occur because of the count data on the response variable with a zero value (Zero-Inflated) which results in overdispersion or a variance value greater than the average. In a pair of data counts that have correlations between response variables and having data with excessive zero values, they can be modelled with Bivariate Zero-Inflated Poisson Regression (BZIPR). The development of the BZIPR regression which has considered spatial factors is called Geographically Weighted Bivariate Zero-Inflated Poisson Regression (GWBZIPR). The weighting function used is the weighting of the Adaptive Gaussian Kernel and the estimation of the parameters of the GWBZIPR model is done using the Maximum Likelihood Estimation (MLE) method. This research was conducted on the number of cases of PB and MB leprosy in North Sumatra Province in 2017. Based on the results of the modelling that the variable that affects the number of cases of PB and MB leprosy in North Sumatra province is the percentage of poor people, the percentage of households with clean and healthy behavior, ratio of medical personnel and percentage of healthy houses.

PERCEPTION OF FINANCIAL EXECUTIVES REGARDING MERGER OF INDIAN BANKS: A CRITICAL STATISTICAL EXPLORATION

Sarbapriya Ray, Gopal Chandra Mondal, Mihir Kumar Pal

Abstract:

The article tries to identify factors affecting merger and acquisition decision in Indian banking sector as well as to find out the motives for mergers Indian banks based on executives’ survey and their perception regarding merger of Indian banks. This empirical research based on executives’ survey finds that new geographical .area, cost advantage,  size advantage, customer base ,inorganic growth, (HR) integration, shareholders’ value, brand quality, financial inclusion, technological advantage, compliance with more regulations, corporate governance, risk perception, CSR, NPA are treated as  the important strategic motives behind  merger of Indian banks   while considering those factors in order of magnitude of computed mean as our empirical result confirms  having surveyed  executives under our study. The ordinal logit model initiates one to infer that most of the respondents consider that corporate governance, in particular, has an important and significant impact on the merging decision of Indian banks. Other notable factors like inorganic growth(IG), Shareholders value(SV), Non- performing assets(NPA), size advantage(SA) and financial inclusion(FI) are not so important factors in deciding merger decision of Indian banks as our ordinal regression results suggest.

GEOGRAPHICALLY WEIGHTED QUANTILE REGRESSION MODELLING ON HUMAN DEVELOPMENT INDEX IN JAVA ISLAND

Neny Kurniawati., Henny Pramoedyo., and Suci Astutik

Abstract:

Quantile regression analysis is a regression method with an approach to dividing data into certain quintiles that may have different predictive values. Although it is not specified as a robust method, quantile regression can be applied to data that containing outliers and has a non-homogeneous variance of errors. If the variance of errors is not homogeneous, it’s likely that a globally generated model won’t be able to explain the entire data so that a locally generated model is needed by including spatial elements. Conditions that are influenced by spatial elements allow for spatial heterogeneity. GWR is a method that can be used to predict model parameters in data that have spatial heterogeneity. To accommodate two aspects at once, namely the the exploration of relation patterns between variables that are influenced by spatial heterogeneity factors and the distribution pattern of response variables, Geographically Weighted Quantile Regression (GWQR) was developed. In this study, the GWQR model was applied to Java Island’s HDI data where its achievement was very diverse and a cause for spatial problem. The weight that used in this research is the Adaptive Gaussian Kernel and the quantile value that used is 0.05; 0.25; 0.50; 0.75; and 0.95. The analysis shows that the GWQR model is better than the global QR model in explaining the relationship between life expectancy (years), school enrollment rates aged 16-18 years (%), percentage of the population with minimum high school education (%), population density (km2/soul), percentage of poor people (%), and expenditure per capita (rupiah) towards the IPM of districts/cities in Java Island. This can be seen from the results of the predictions produced by the GWQR model which is closer to the actual IPM value than the prediction results generated from QR models globally and also base on the value of RMSE. The RMSE value of GWQR model for each quantile are less than RMSE value of global QR.

Agus Sugiarto and Taufiq Rochman

Abstract:

The FRP (fiber reinforced polymer) using on structure inovation of civil engineering have been learned and discussed in a very short time. FRP has been expanded to be smart material that ready for replace concrete and steel. The lack of steel and concrete on flexural case for length that dominate its selfweight from nominal flexural capacity left over and dominate then live load. Many research use FRP as retrofit reinforcement which using strip or prestressed strip carbon system, but it is rarely focused on fully FRP application so that proposed a U-shape FRP girder to hold the flexure. Reinforced FRP beam is made from E-glass fiber type by using unsaturates polyester resin as a matrix material. Composite beam is shaped from one set of angled 0 uniaxial mat and angled 45 biaxial mat. Pull wing U-profile on lower section has configuration lay-up of 17 mat layers [453/04/453/04/453], and the other section have configuration lay-up of 9 mat layers mat [45]9. The beam is variated on its height, they are 15 cm, 12.5 cm, and 10 cm in a row for A, B, and C beam. Girder length is set on 2000 mm and flexural load 3 centered node from 0 untul 105Kn that given quasi-staticly. Load and flexural is recorded manually but the strain is recorded automatically using aqcuisition system data. On centered load more than 0 Kn until 105 Kn, the result is obtained by flexural average on 47 mm and the tensile strain average on 0.0018. Deflection and strain sequence from small until high are A, E, and C beam. But the shear load damage and local support caused of centered load from the damage sequence visually from the smallest until highest are C, B, then A.

Marni

Abstract:

Maternal and child health is still a concern in Indonesia. Many efforts have been made to lessen maternal mortality (MMR) in Indonesia, such as improving antenatal care in all health care facilities with good quality and reaching all target groups, gradually increasing labor service by professional staff, increasing the high risk of pregnant women and implementing a referral system and improving a good quality service of neonatal care. This study aims to determine the relationship between health facilities’ affordability and health care selection for pregnant women, understand the behavior of pregnant women in making decision and utilizing health care, and knowing the extent to which the knowledge of pregnant women about health care information systems. This study took place in 15 villages which is selected by random sampling technique, whereas the sample is consisted of 358 respondents obtained by “purposive sampling” method. Data collection was conducted using questionnaire and data collection sheets and analyzed descriptively. The affordability of health facilities is the main consideration in selecting labor service. The decision made by pregnant women in selecting treatment still requires consideration of others, especially spouse, free cost, and there are still many of those who use the help of traditional labor attendants. Information systems regarding health care are already known by public such as BPJS, Jamkesmas / Jampersal and Jamkesda as a health services insurance that are widely used by the public.
