Analyze Data

One of the actively developing areas of modern computational problems is data analysis. The studied data have a different structure, which causes certain difficulties in the process of smoothing and analysis. This fact entails the need to search for new universal algorithms for data processing and create computer programs that analyze data of various nature. Today, a widely used method of data processing is regression modeling. It is used in problems of pattern recognition, classification, dimensionality reduction, and many others. The literature describes various methods of constructing regression models, the basis of which is the optimization of a certain indicator — the quality functional. A very important requirement for the quality of such models is the absence of outliers (outliers) in the data. This article discusses a method for examining a sample for outliers. The obtained algorithm can be applied to regression models estimated by the most common methods (least squares method, least modulus method). The mathematical basis of this procedure is the Legendre transformation, which provides computational accuracy in computer implementation. The adequacy of the obtained algorithm was investigated on a number of test samples. All tests were positive in terms of emissions. The MatLab system is used to develop a set of programs, which allows the building of various regression models and evaluation of the original sample for sharply distinguished observations.

Research conducted at the Office of Archives and Library of Padang Pariaman Regency aims to find out the data processing system library and data archiving. All data processing is done is still very manual by using the document in writing and there is also a stacking of archives on the service. By utilizing library information systems and archives that will be applied to the Office of Archives and Library of Padang Pariaman Regency can improve the quality of service that has not been optimal. This research was made by using System Development Life Cycle (SDLC) which is better known as waterfall method. The first step taken on this method is to go directly to the field by conducting interviews and discussions. This information system will be able to assist the work of officers in terms of data processing libraries and facilitate in search data archives by presenting reports more accurate, effective and efficient.

The main objective of this study was to investigate the association between final-year students’ anxiety level and quality of life (QOL) with their academic achievements. A longitudinal study was performed in regular schools and in high-rated gymnasiums at the beginning and at the end of the school year. Multiple linear regression models were built for the association between level of anxiety/QOL with academic achievements. Type of school and gender—but not the level of anxiety—were the main predictors of academic achievements of 287 adolescents (e.g., for mathematics, the effect estimates were: β = −1.71 [95% confidence interval −2.21; −1.21]; β = −0.50 [−0.95; −0.06], β = 0.09 [−0.02; 0.20] for the type of school, gender, and changes in level of anxiety, respectively). To conclude, particular efforts should be made to reduce the level of anxiety in girls, especially those that study in high-rated schools.

Objective The study aimed to explore physician views on whether extremely early newborns will have an acceptable quality of life (QOL), and if these views are associated with physician resuscitation preferences. Study Design We performed a cross-sectional survey of neonatologists and maternal fetal medicine (MFM) attendings, fellows, and residents at four U.S. medical centers exploring physician views on future QOL of extremely early newborns and physician resuscitation preferences. Mixed-effects logistic regression models examined association of perceived QOL and resuscitation preferences when adjusting for specialty, level of training, gender, and experience with ex-premature infants. Results A total of 254 of 544 (47%) physicians were responded. A minority of physicians had interacted with surviving extremely early newborns when they were ≥3 years old (23% of physicians in pediatrics/neonatology and 6% in obstetrics/MFM). The majority of physicians did not believe an extremely early newborn would have an acceptable QOL at the earliest gestational ages (11% at 22 and 23% at 23 weeks). The majority of physicians (73%) believed that having an extremely preterm infant would have negative effects on the family's QOL. Mixed-effects logistic regression models (odds ratio [OR], 95% confidence interval [CI]) revealed that physicians who believed infants would have an acceptable QOL were less likely to offer comfort care only at 22 (OR: 0.19, 95% CI: 0.05–0.65, p < 0.01) and 23 weeks (OR: 0.24, 95% CI: 0.07–0.78, p < 0.02). They were also more likely to offer active treatment only at 24 weeks (OR: 9.66, 95% CI: 2.56–38.87, p < 0.01) and 25 weeks (OR: 19.51, 95% CI: 3.33–126.72, p < 0.01). Conclusion Physician views of extremely early newborns' future QOL correlated with self-reported resuscitation preferences. Residents and obstetric physicians reported more pessimistic views on QOL.

Abstract This article contributes a framework for the quality assessment of imputations within a broader structure to evaluate the quality of register-based data. Four quality-related hyperdimensions examine the data processing from the raw-data level to the final statistics. Our focus lies on the quality assessment of different imputation steps and their influence on overall data quality. We suggest classification rates as a measure of accuracy of imputation and derive several computational approaches.

В статье рассматривается деятельность автотранспортного предприятия ООО ЦЗК «Логистик». Проведено моделирование производственного процесса объекта исследования с использованием множественного корреляционно-регрессионного анализа. Для проведения прогнозирования были отобраны шесть результативных и пять факторных признаков, характеризующих производственную деятельность объекта исследования. Были построены множественные регрессионные модели, связывающие результативные показатели эффективности функционирования автосервиса с влияющими на них производственными факторами. Проведённый корреляционный анализ показал, что между результативными и факторными признаками существует сильная прямая связь. Осуществлено прогнозирование шести основных результативных признаков, характеризующих производственную деятельность предприятия на основе двух сценариев с применением построенных в ходе исследования регрессионных моделей. Полученные результаты исследования позволили сделать ряд рекомендаций, способствующих улучшению финансового состояния предприятия. Применение полученных в результате исследования моделей позволит автосервисному предприятию обеспечить высокое качество и производительность работы всех производственных зон, а также улучшить качество управленческих решений. The activity of the motor transport enterprise OOO BRC "Logistics" is discussed in the article. The process simulation of the research subject was conducted using multiple correlation-regression analysis. For forecasting six resulting and five factor features were selected that characterize the production activity of the research subject. Multiple regression models were constructed linking the resulting features of the functioning of the car-care service with the production factors affecting them. The conducted correlation analysis showed that there is a strong direct connection between the resulting and factor features. Six main resulting features characterizing the production activity of the enterprise based on two scenarios were predicted using regression models constructed during the research. The results of the research made a number of recommendations contributing to the improvement of the financial condition of the enterprise. Using the models obtained as a result of the research will allow the car-care service enterprise to ensure high quality and productivity of all production zones as well as improve the quality of management decisions.
