The work deals with the impact assessment of selected parameters of residential buildings on their energy performance. Within the application of the theory of statistics database of selected residential buildings is analyzed in terms of different features that characterize it. In particular, the thermal insulating properties and individual sub-items in the energy balance are analyzed. Then the measured rate dependence of selected parameters affecting energy performance is examined using correlation and regression analysis. The results are applied in the development of computational tools for evaluating energy flows in the building.

Šiame darbe pateikta nuosekli statistinės analizės metodika tyrimo rezultatams apdoroti ir nagrinėjamos kriterijų taikymo galimybės. Pasiūlyti kriterijai ryškiai išsiskiriantiems duomenims atmesti, nurodyti kriterijai tyrimo rezultatų atsitiktinumui ir nepriklausomumui bei pasiskirstymo pagal normalųjį dėsnį hipotezėms tikrinti, atlikta tyrimo rezultatų koreliacinė ir regresinė analizė ir pasirinkto regresinio modelio adekvatumo tikrinimas panaudojus Fišerio kriterijų. / The paper provided a consistent statistical analysis techniques to process the results of the study and analyze the possibility of application of the criteria. Propose criteria for emissions during the data significantly rejected by the criteria set out in the survey results to chance and the independence of the distribution under the normal law of hypotheses to verify the results of research carried out correlation and regression analysis and the selected regression model for testing the adequacy of using the Fisher criterion.

Neste trabalho foi proposto um modelo de regressão para dados com censura intervalar utilizando a distribuição Weibull-exponenciada, que possui como característica principal a função de taxa de falha que assume diferentes formas (unimodal, forma de banheira, crescente e decrescente). O atrativo desse modelo de regressão é a sua utilização para discriminar modelos, uma vez que o mesmo possui como casos particulares os modelos de regressão Exponencial, Weibull, Exponencial-exponenciada, entre outros. Também foi estudado um modelo de regressão para dados de sobrevivência grupados na qual a abordagem é fundamentada em modelos de tempo discreto e em tabelas de vida. A estrutura de regressão representada por uma probabilidade é modelada adotando-se diferentes funções de ligação, tais como, logito, complemento log-log, log-log e probito. Em ambas as pesquisas, métodos de validação dos modelos estatísticos propostos são descritos e fundamentados na análise de sensibilidade. Para detectar observações influentes nos modelos propostos, foram utilizadas medidas de diagnóstico baseadas na deleção de casos, denominadas de influência global e medidas baseadas em pequenas perturbações nos dados ou no modelo proposto, denominada de influência local. Para verificar a qualidade de ajuste do modelo e detectar pontos discrepantes foi realizada uma análise de resíduos nos modelos propostos. Os resultados desenvolvidos foram aplicados a dois conjuntos de dados reais. / In this study, a regression model for interval-censored data were developed, using the Exponentiated- Weibull distribution, that has as main characteristic the hazard function which assumes different forms (unimodal, bathtub shape, increase, decrease). A good feature of that regression model is their use to discriminate models, that have as particular cases, the models of regression: Exponential, Weibull, Exponential-exponentiated, amongst others. Also a regression model were studied for grouped survival data in which the approach is based in models of discrete time and in life tables, the regression structure represented by a probability is modeled through the use of different link function, logit, complementary log-log, log-log or probit. In both studies, validation methods for the statistical models studied are described and based on the sensitivity analysis. To find influential observations in the studied models, diagnostic measures were used based on case deletion, denominated as global influence and measures based on small perturbations on the data or in the studied model, denominated as local influence. To verify the goodness of fitting of the model and to detect outliers it was performed residual analysis for the proposed models. The developed results were applied to two real data sets.

Целью работы является разработка методического подхода к оценке эффективности операционной деятельности телекоммуникационной компании. В основе подхода – динамический анализ ключевых факторов операционной деятельности, проведение корреляционно-регрессионного анализа между операционными параметрами и показателями эффективности, а также расчет интегрального показателя. Разработанный методический подход к оценке операционной деятельности телекоммуникационной компании позволяет повысить точность расчетов, объективность комплексной оценки и оценить эффективность операционной деятельности. / The aim of the work is to develop a new pricing mechanism at woodworking enterprises. The mechanism is based on the calculation and further accounting in the pricing process of the waste coefficient, which characterizes the volume of waste in the sawmill, depending on such parameters of the final product as the thickness and width of lumber. The developed pricing mechanism makes it possible to more accurately determine the cost of production, form favorable offers to counterparties and concentrate the efforts of sales managers on the most profitable positions of the assortment.
