Research Expert Solutions Launches 15 Advanced Statistical Software Programs for Universities
Research Expert Solutions (RES) is proud to announce the official release of 15 groundbreaking statistical software programs designed to transform how universities conduct data analysis, research, and academic instruction. Developed by Fitzgerald Witika, Economist and Chief Executive Officer of Research Expert Solutions, this suite of desktop applications represents a major step forward in making high-level data analytics accessible, affordable, and fully optimized for academic environments.
For years, universities have faced challenges in accessing advanced analytical tools due to the high costs and fragmented nature of software licensing. This new initiative from RES offers an innovative solution — allowing universities to subscribe to all 15 statistical software programs as a single bundle at a fraction of the cost of individual subscriptions. Through this institutional model, lecturers and students can seamlessly access powerful offline analytical tools across research, teaching, and coursework without relying on external cloud systems or expensive international licenses.
The 15 software programs were developed to cover a comprehensive range of analytical needs. Witika F-Correlations delivers deep correlation analysis with over 35 visualization types, while FitzStatistics integrates qualitative and quantitative analytics into one unified, no-code environment. FitzProanalysis combines econometric, forecasting, and machine learning capabilities with models such as ARIMA, VAR/VECM, and GARCH, making it an ideal companion for economics and business research. For students of game theory and behavioral economics, Fitzeconomic Games introduces an interactive, no-code platform for modeling and analyzing strategic decision-making scenarios.
Other highlights include WitikaPythonalysis, a powerful visualization-first studio for categorical and mixed data, and the Witika Literature Search Engine (WLSE), which revolutionizes how researchers conduct systematic literature reviews and visualize bibliometric data. In the field of artificial intelligence and predictive modeling, Witika Machine Learning offers a point-and-click interface for building, evaluating, and interpreting models with ease.
The bundle also features several specialized analytical tools under the WitikaStats family — including Advanced Visualization & Storytelling, Time Series Analysis Suite, Scatter Matrix, Machine Learning Version, Correlation Ellipse Plotter, Contour Analysis, Stationarity Diagnostics, and the Advanced Correlation & Pair Plot Specialist. Each application is designed to produce publication-ready outputs, high-resolution visuals, and reproducible project files — empowering researchers, lecturers, and students to conduct data analysis with greater precision and efficiency.
What sets these software programs apart is their offline usability and built-in licensing security. Each installation is authorized through secure hardware binding, ensuring that the applications remain exclusive to licensed university computers and registered users. This eliminates unauthorized sharing while allowing universities to maintain full control over usage and compliance.
By subscribing to this bundle, universities not only gain access to state-of-the-art analytical software but also open doors for capacity building and research excellence. Lecturers can use the tools to produce publishable research with modern statistical rigor, while students benefit from hands-on exposure to advanced methods that enhance their dissertations and employability in data-driven industries.
The institutional subscription model allows a university to provide full access to all 15 programs for its students and staff at a single monthly fee — offering a sustainable, cost-effective alternative to traditional software licensing. Universities may optionally integrate a modest technology access fee to recover costs or generate additional revenue while enhancing the digital learning experience.
Through this initiative, Research Expert Solutions continues to fulfill its mission of empowering Africa’s academic community with locally developed, world-class analytical tools.
