Loglet Lab Software Implementation

The algorithms and methods described in this paper were originally implemented in ANSI C and the mathematics package MatLab [13] in a Unix computer enviroment. Many of the algorithms are based on the C source code presented in Press, et al. [17] and Engeln-Müllges-Uhlig [5].

The Loglet Lab software project's goal is to integrate these algorithms into a single GUI ⁶application for use on a modern operating system, namely Microsoft Windows 95 and NT. To this end, Loglet Lab was built in Microsoft's Visual C++ integrated development environment and features spreadsheet and charting modules developed by Visual Components. This provides a familiar interface for data entry as well as instant charting. Loglet Lab allows users to cut-and-paste their data between spreadsheets such as Excel and the graphics between business presentation programs such as PowerPoint. Appendix B describes the current state of this project.

Other advanced regression methods (e.g., Marchetti's method for robust weighted regression, or $\mathcal{CM}$ regression) have been implemented in C or MatLab, but they have yet to be ported to the Win32 environment.
