Context and relevance. Eco-anxiety is the anxiety arising in connection with real and possible natural changes and disasters. Eco-anxiety is a significant destabilizer of human activity and therefore needs to be monitored or intervened, which requires a tool to assess its severity. Objective. The present study is aimed at adapting the Hogg Eco-Anxiety Scale (HEAS) ...

Under limited data, the classical cohort method for the creation of migration matrices does not fully reflect the dynamics of the credit quality of the objects within the sample. This problem is exacerbated for objects of lower credit quality less represented in the sample. This paper investigates a continuous time approach to the creation of ...

This paper proposes a method of designing a statistically distinguishable rating scale
that is not excessive in relation to the existing observation statistics. This allows for
more stable validation with a fixed maximum number of violations of the Wald criterion
compared with the excess scales usually used by banks. The increased validation
robustness will reduce the calibration probability of ...

The Basel Internal-Ratings-Based (IRB) approach allows banks to use sufficiently good credit risk models for the daily computation of their capital adequacy ratio. However, being sufficiently good does not naturally mean being perfect. Conventionally, risk managers increase the mean probability of default (PD) and loss given default (LGD) values by some margin when developing a model. They expect that it is sufficient to offset for potential model risk. This add-on, ...

Transportation systems are complicated and deal with significant problems. With the pool of possible solutions being wide, extensive transportation planning has to be involved. However, planning based on expert opinions is significantly limited in terms of rapidity, accuracy, and confidence. Computer-aided design and automated decision-making systems are the next step to ensure transportation system development ...

Identification with the city not only supports the psychological wellbeing of the resident, but also becomes a resource for the development of the city, because committed citizens are more motivated to preserve and protect their city. Meanwhile, there are few ways to measure this phenomenon, and the available ones have limitations or have not been ...

Background: the effectiveness of a primary screening system for psychiatric disorders in the population can be enhanced
by using short scales with high psychometric properties. Aim: to evaluate the psychometric properties of the Russian version of the Kessler Psychological Distress Scale. Participants and Methods: the data from three online surveys conducted as part of the study ...

WAM, SWAN and WAVEWATCH III® were implemented to the Finnish archipelago with a 0.1 nmi grid. A comparison with coastal wave buoy observations showed that the models agreed on the significant wave height, with biases and root-mean-square-errors (RMSE) differing at most 0.06 m. In a general sense, WAM propagated most long wave energy into the archipelago, while SWAN ...

In 2016, the Bank of Russia developed two ordinances to set forth a procedure using a limited sample of loans to conclude whether the level of loss provisions in the portfolio of uniform loans is sufficient or not and whether the bank’s capital is adequate.
The existing procedure of reserve sufficiency evaluation previews as a rule considering only a part of the loan portfolio and transfer (extrapolation) of the provision thus assessed for the overall portfolio. Moreover, the acting approach to define the minimum loan sample size assumes the absence of the default correlation.

Кредитоспособность заемщиков существенно различается от региона к региону, при этом построить скоринговую модель для каждого региона невозможно. Для калибровки скоринговых моделей с учетом региона необходимо учесть макроэкономиче- ские факторы, оказывающие влияние на вероятность дефолта (PD). Какими могут быть подходы к построению макроэкономи- ческих моделей для получения прогнозов вероятности дефолта в регионах? Как использовать метод ...

The study focuses on how modern GEC systems handle character-level errors. We discuss the ways these errors effect the performance of models and test how models of different architectures handle them. We conclude that specialized GEC systems do struggle against correcting non-existent words, and that a simple spellchecker considerably improve overall performance of a model. ...

Описанный подход к валидации риск-менеджмента розничного портфеля применялся в крупнейших банках и дал безупречно обоснованный результат, ускоривший коррекцию риск-политик в существенных сегментах розничных продуктов вплоть до закрытия одних и расширения планов размещения других. На основе оценки экономической выгоды от усиления риск-менеджмента с учетом текущих и плановых объемов могут быть обоснованно увеличены бюджеты на расширение аналитического ...

The paper proposes new second-order accuracy metrics for scoring/rating models, which show the target preference of the model - it is better to diagnose "good" objects or better to diagnose "bad" ones for a constant generally accepted predictive power determined by the first-order metric - the Gini index. Two metrics proposed, they have both an ...
