Statgraphics Centurion

Statgraphics Technologies, Inc. develops the Statgraphics family of analytics products, with Statgraphics Centurion as its flagship Windows desktop application for statistics, visualization, SPC, DOE, forecasting, and (in recent versions) machine learning. The company is privately held and headquartered in The Plains, Virginia (USA). Statgraphics has a long history in PC statistics software and is notable for blending graphics with every statistical procedure and for guidance features (StatWizard™, StatAdvisor™) that make results understandable to non‑statisticians. 

The current mainstream release line is Version 19 (with frequent build updates), while Version 20 is in public beta and focuses on additional ML and visualization capabilities. Statgraphics’ distribution model uses a global network of dealers for international sales and support.

Statgraphics’ origins date to 1980, when Dr. Neil W. Polhemus (then at Princeton University) created the software as a teaching tool; it was commercialized in 1982, becoming one of the earliest PC‑based statistics packages. Over the decades, Statgraphics expanded from basic statistics to a broad professional suite encompassing regression/ANOVA, multivariate analysis, SPC, DOE, reliability, forecasting, Monte Carlo simulation, and, more recently, machine learning. The company has kept a focus on a GUI‑first experience that reduces reliance on scripting and emphasizes interpretability.

The firm’s long product lineage (Centurion XVI → XVII → XVIII → XIX → 20 beta) shows iterative growth: expanding procedure counts, modernizing the interface (ribbon UI, dashboards), and progressively integrating with external ecosystems such as R and Python.

Statgraphics Technologies, Inc. is privately held. There are no public disclosures of external venture funding rounds or company valuation in official materials or credible directories. Public profiles (e.g., Wikipedia and corporate listings) consistently describe Statgraphics as a privately held software company without published financing data. Accordingly, funding and valuation should be considered not publicly disclosed.

Primary products (current/legacy lines):

• Statgraphics Centurion (Windows desktop) — full statistical suite with 290+ procedures, modern ribbon UI, dashboards, data visualization, DOE wizardry, SPC, forecasting, reliability, multivariate methods, and ML additions; notable guidance tools include StatAdvisor™ (plain‑language result interpretation) and StatWizard™ (method selection).
• Statgraphics Stratus — a cloud/web offering referenced in product family materials. 
• Statgraphics Sigma Express — Microsoft Excel add‑in for statistical/quality tools in familiar spreadsheets.
• Statgraphics Web Services / StatBeans (developer‑oriented components referenced across legacy/product literature).

Feature depth highlights:

• Statistics & Modeling: descriptive stats; hypothesis testing; regression/ANOVA; GLMs; quantile and piecewise regression; zero‑inflated models; mixture distributions.
• DOE: screening, response surface, mixture, robust parameter, D‑optimal, definitive screening, computer‑generated designs, alias‑optimal (v19), and design augmentation; multi‑response optimization.
• SPC & Quality: 27+ control charts (including multivariate), capability analysis, gage R&R and measurement systems analysis, acceptance sampling, Six Sigma toolset.
• Time Series/Forecasting: exponential smoothing, ARIMA, automatic model selection, seasonal/trend decomposition.
• Monte Carlo & Simulation: general simulation models; ARIMA simulation; random number generation (dozens of distributions); multivariate normal sampling.
• Visualization: dashboards, Pareto, radar/spider, spiral plots, demographic maps, treemaps and sunbursts (v20), waterfall and Venn/Euler diagrams; interactive graphics across procedures.
• Ecosystem: Python and R integration for code execution, data exchange, and library access (e.g., scikit‑learn).
• Languages: English, French, German, Italian, Spanish (switchable UI/output editions).

• Centurion 19 (major modern update):
  • New ribbon UI, procedure dashboard, 15+ new procedures, Python interface, expanded visualization (waterfall, Venn/Euler), decision forests, SVMs (v19.2), equivalence/noninferiority testing, zero‑inflated models, and alias‑optimal DOE; ongoing builds such as 19.7.01 (Apr 29, 2025) show active maintenance. 
• Version 20 (beta):
  • 10 supervised ML algorithms, a Supervised ML Assistant with cross‑validation and ensembling, new business charts (Gantt, treemap, bullet, sunburst, funnel), additional quality procedures (accelerated life testing, Type‑1 gage, dissolution, Levey‑Jennings), anomaly detection and clustering methods; available to v19 licensees for beta download.

Public‑facing materials emphasize a culture of accessibility, clarity, and practitioner impact:

• Ease of use & education: Statgraphics was among the first to integrate graphics throughout procedures; features like StatAdvisor™ generate natural‑language interpretations, and StatWizard™ lowers the expertise barrier—signaling a culture that prioritizes usability and learning. 
• Customer enablement: Training resources (videos, webinars, guides) and a dealer ecosystem suggest a service mindset catering to a global, practitioner‑heavy audience across QA/engineering/R&D. 
• Continuous improvement: Iterative releases, public beta programs, and frequent version builds reflect a focus on incremental enhancement and responsiveness to user needs. 

Statgraphics is used broadly across manufacturing (chemicals, pharma, medical devices, autos, food/CPG), mining & environmental, government/education, and aerospace (NASA)—sectors that value SPC, DOE, and validation‑friendly desktop analytics. The company maintains an active LinkedIn presence and historically a Statgraphics Community on LinkedIn, along with webinars and documentation aimed at practitioner communities. International reach is supported by regional dealers rather than owned offices.
