QStudioMetrics is a high-performance C++ toolbox for exploratory data analysis, chemometrics, and multivariate statistics. It provides a bridge between complex algorithms and intuitive discovery, allowing researchers to interact with their data without writing a single line of code.
- Interactive Exploratory Analysis: Real-time plotting and manipulation of PCA and CPCA models.
- Advanced Regression: Comprehensive support for PLS and MLR with automated validation.
- Robust Classification: Linear Discriminant Analysis (LDA) with high-accuracy results.
- Validation Suite: Built-in K-Fold cross-validation, Leave-One-Out, and Y-Scrambling to ensure statistical significance.
- High Performance: Native C++20 engine powered by
libscientificfor handling large datasets efficiently. - Cross-Platform: Seamlessly runs on Linux, Windows, and macOS (Intel/Silicon).
Discover how to separate wine cultivars in 30 seconds:
- Import: Launch QStudioMetrics and go to
File > Import Data. Selectexamples/wine.csv. - Model: Navigate to
Models > PCA. Select all chemical variables (Alcohol, Malic acid, etc.) and clickCompute. - Discover: Open the
Scores Plot. You will see three distinct clusters representing different wine cultivars based on their chemical profile!
- C++ Compiler: Supporting C++20 (GCC 10+, Clang 10+, MSVC 2019+)
- CMake: >= 3.22
- Qt6: Core, Core5Compat, Gui, Widgets, Sql, PrintSupport, Concurrent, Charts
- libscientific: (Automatically downloaded during build if not found)
- Pandoc & LaTeX: (Optional) Required only for building the PDF/HTML documentation
