models to be used. In this paper, a pseudo-observation approach was applied to single-event and competing-risks analysis, with special attention paid to the properties of the pseudo-observations. In the empirical part of the study, the use of regression models based on pseudo-observations in credit-risk assessment was investigated. Default, defined as a delay in payment, was considered to be the event of interest, while prepayment of credit was treated as a possible competing risk. Credits that

advantageous to build local regression models than a global model. Additionally, we propose a local feature selection via regularization. The empirical research carried out on three data sets from real estate market confirmed the effectiveness of this approach. We paid special attention to the model quality assessment using cross-validation for estimation of the residual standard error.

research. It systematically presents the strategies to estimate the size of personal networks. Finally, it describes how to fit statistical analysis to relational data, including regression models, multi-level models, and longitudinal models. Consequently, these are three books that complement each other. With these three volumes, the reader can have a comprehensive and updated overview of the study of the structure of personal networks. Below we focus on evaluating two of the fundamental contributions

We consider hierarchical regression models for circular data using the projected normal distribution, applied in the development of weights for the Access Point Angler Intercept Survey, a recreational angling survey conducted by the US National Marine Fisheries Service. Weighted estimates of recreational fish catch are used in stock assessments and fisheries regulation. The construction of the survey weights requires the distribution of daily departure times of anglers from fishing sites

Children’s Anxiety Scale; DASS, Depression Anxiety Stress Scale; C, Child; M, Mother; F, Father. *Correlation is significant at the p < 0.05 level; **Correlation is significant at the p < 0.01 level; ***Correlation is significant at the p < 0.001 level
Three multiple regression models were run (see Table 3). In the first model for child self-rated anxiety symptoms (SCAS-C), the predictors were mothers’ and fathers’ self-rated internalizing symptoms (DASS), child age, and child gender. This model

An analysis was carried out on the efficiency of development of logistics and trade, impact of development of logistics on international trade. Based on the analysis of international indices of logistics efficiency, international trade conditions and regression models, problems and reasons for lagging have been identified that affect the

Procedure
Data for this study were collected from Syrian immigrant adolescents. Both ethical permissions for the study and the consent of school principals were obtained before the study. Parental consent form (in Arabic and Turkish) was sent to the homes, and none refused
