Models for a continuous risk outcome has a wide application in portfolio risk management and capital allocation. We introduce a family of interval distributions based on variable transformations. Densities for these distributions are provided. Models with a random effect, targeting a continuous...

This book describes the estimation and use of Klein Model I, including the formation of the individual equations, the data used for its estimation and the methodology of the construction and use of the model involving the MODLER software and an electronic computer

This paper studies the sequential sampling scheme as a solution to the problem of aliasing, where the sampling interval is restricted to a minimum allowable value. Sequential sampling is analyzed and it is proved that when the sampling ratio is an integral number, the associated spectral...

In this paper we present compelling evidence from a detailed analysis of historical prepayment data to demonstrate that a mortgage cohort remembers the level of the previous mortgage rate troughs experienced by the cohort. This is a general property, observed ubiquitously, that inescapably leads...

In the present document it is exposed in an abstract way the models of credit portfolioes CreditMetricsTM, KMV, CreditRisk+, Credit Portfolio View in such a way that they could be calibrated and implemented in financial institutions where the quality and quantity of credit information is scanty,...

The monograph is devoted to use of distributed and parallel calculations in MATLAB interface. The technology is approved on standard problems of linear algebra. The industrial approach for identification of mathematical models of difficult systems on the basis of MATLAB parallel technics is...

After entering the European Union (EU) Latvia faced new possibilities in international labor market. In 2004 several member states opened their labor markets to workers from Latvia. The largest amount of labor force went to Ireland, Great Britain and Sweden. In these countries salaries were...

The paper discusses the influence of the global economic crisis on the Latvian economy. Using the system dynamics approach and models produced beforehand, various development scenarios of tax policy, householder crediting, and the job market are analyzed. Produced models allow to obtain...

The coronavirus has deleteriously affected a great majority of countries in the world. Developed societies such as the United States and the majority of Western countries have had the highest rates of mortality because of the pandemic. Sub-Saharan Africa, on the other hand, has been the...

In a paper construction branch forecasting model which allows to estimate the industry development problems is shown. Difference from anthers models, in given paper the main attention is turned to the building of the living area. Model stands from sub model (blocks): amount of apartments, real...
