STATISTICA 8.0 was a 32‑bit application that ran on Windows XP, Vista, and Windows 7. It was available in several editions:
Deep integration with open-source environments, allowing users to run R and Python scripts directly within Statistica workflows. 2. The 80/20 Rule in Data Science and Statistics
Many statistical offices publish numbered reports (e.g., "Statistica report n. 80/2021"). Examples:
