Haxial Calculator is a high precision mathematical assistant that evaluates normal (infix) expressions to practically any accuracy. Results can be viewed in normal, fraction, or scientific forms, and it allows you to work in any radix. Worksheets enable you to solve larger problems in a more suitable environment, as well as allowing you to save your work. It also incorporates unit and radix conversion utilities and complete support for variables. Haxial Calculator employs a user interface that allows you to freely type expressions with the keyboard instead of mimicking the button presses of a hand-held calculator.
CCruncher is a project for the simulation of large portfolios of SME loans where the unique risk is the default risk. The method used to determine the distribution of losses in the portfolio is the Monte Carlo algorithm, because it allows you to consider multiple variables, such as the date and amount of each payment. The obligors' default times are simulated using a copula with given survival rates and correlations.
The MATNEM Toolbox is a set of MATLAB objects and classes which provides an interface to the Numerical Econometrics Library, a library of econometric routines written in the C language. The aim of the project is to provide an easy, quick, and object-oriented interface for applied econometric analysis. The NEM library also ensures a good level of performance. Among other features, the MATNEM toolbox contains time series data objects, ultra high-frequency data management algorithms, nonlinear estimation routines (ARMA, multiplicative error models (GARCH, ACD)), and frequentist model averaging algorithms (linear regression model, multiplicative error models (GARCH, ACD)).
