There are three different Editions of STATGRAPHICS

• Standard Edition: provides Statistical Analysis for Exploratory Data Analysis, ANOVA and Regression, Data Management, Graphics.
• Quality and Design: Standard Edition + Statistical Quality Control + Design of Experiments
• Professional: Standard Edition + Quality and Design + Time Series + Advanced Regression + Multivariate Statistics
  

StatAdvisor -The StatAdvisor provides easy-to-understand interpretations of your most complex analyses. Helps you interpret your results. Determines if the results are statistically significant Highlights any possible flaws in the analysis. Adds credibility to your reports with expert interpretations printed alongside your results.

StatFolio - The StatFolio is an entirely new way to save and reuse your analyses. Beyond macros. Beyond editing code. With the StatFolio you run an analysis that you know you'll need to run again soon. So, with a couple of mouse clicks, you save the complete analysis in a StatFolio. Variable names, graphics settings, analysis options, and all. Then, when you're ready to rerun the analysis on a new set of data, you just recall the StatFolio, choose new variables if you like, and watch your tables and graphics update on the screen automatically. It's as fast and easy as saving a file. And, it's only available with STATGRAPHICS Plus.

Interactive Graphics - STATGRAPHICS Plus gives you access to graphics in every procedure. Whether you're fitting a stepwise regression model or tabulating the results of a customer survey, a pop-up selection of related graphs is just a mouse click away. And, we're talking serious interactive graphics. Graphics you can get your hands on.
Graphics become an analytical tool, not just a presentation device Identify a data point or query its location in the data file Jitter points on a graph to determine the density of the data points Brush to differentiate points when you add an additional variable Quickly and easily explore your data, discovering new relationships while your graph is displayed on the screen Print multiple graphs per page on any device supported by Windows, including laser printers, plotters, and Postscript devices Add information or enhance a graph with additional labels and your choice of borders, frames, grids, points, colors, and fonts Customize all your graphics with user-defined settings

A selection of the graphics are shown in our Graphics Examples.

StatWizart - The StatWizard guides new or casual users in selecting the appropriate analysis for collecting and analyzing data. Users have the option of working with our standard menu or commonly used Quick Pics.

StatLink - StatLink lets you tie StatFolios directly to data sources from spreadsheets, databases, and measuring devices such as digital micrometers via linking software. Query the data source when the StatFolio is opened or at regular user-specified intervals.

SnapStats - New in Version 5, SnapStats, provide a faster, easier way to generate a one-page summary of your favourite analysis. Simply select the SnapStats you need, define the data and the system creates a pre-formatted page containing both numeric and graphical results

STATGRAPHICS Plus gives you access to customizable graphics in every procedure.

STATGRAPHICS Plus Quality and Design offers the Standard Edition plus facilities for Statistical Quality Control and Design of Experiments.

Statistical Quality Control

The Quality Control Module for STATGRAPHICS provides about 20 analyses to use for Statistical Quality Control. Below there are some examples.

Pareto Analysis

The Pareto Analysis allows you to produce a Pareto Chart, which is a histogram for categorical data. Manufactures often use this tool, together with attributes charts, to identify and rank order the most important causes of a problem within a process. Pareto Charts are also used to track the progress of changes to a process.

Shewhart Control Charts

Shewhart control charts helps to determine statistical control for samples taken at reasonable intervals, they also detect assignable causes and shifts in an attempt to maintain the process "in control" status, and eliminate the nonrandom variability of the process. The Quality Control Module for STATGRAPHICS Plus offers four set of variables control charts: X-bar and R Charts, X-bar and S (or S2) Charts, and individual Charts. It's possible pre-specify the control limits, or let STATGRAPHICS Plus calculates them automatically. It's also possible, while an Initial Study is running, exclude subgroups without altering the data. The new version includes a new Tolerance Chart, for those situations when you need to go beyond statistical aggregates and look at the individual data points that lie behind the picture.
The Quality Control Module for STATGRAPHICS Plus offers four attributes control charts: p Charts, np Charts, c Charts and u Charts. The type of chart you use depends on the way you count the defects.And like for the Variables Control Charts, there's a full range of text- and graphic-based options.

Time-Weighted Control Charts

The time-weighted charts are based on subgroup statistics or individual observations. The time-weighted charts are similar to control charts, however they differ because they incorporate the past history of the process, are more sensitive to small and gradual changes in the process and are based on the moving statistics.

Multivariate Control Chart

The Multivariate Control Chart Analysis lets construct control charts for samples that have more than one variable in which you can correlate different measurements. This analysis is based on Hotelling,s T-squared statistic and assumes that the data come from a multivariate normal distribution.

Gage R&R

The Gage R&R helps you assess the quality of the measurement system. Analysing the repeatability and reproducibility components of gage variation is a breeze in the QC module. A capable measurement system with little variability is helpful in accurately measuring process control and capability.

Design of Experiments

Experimental Design is a scientific approach that allows an experimenter to better understand a process and how the inputs affect the outputs. The primary reason for using any designed experiment is to use data that can provide answers to well thought out questions.

Screening Designs

The STATGRAPHICS Plus Screening Designs procedure allow you to test all possible combinations of a large number of environmental factors. Or perform a fractional factorial design or a Plackett-Burman design on only part of the full design - reducing experimental time and costs. A wide range of tables and charts are included to help with the interpretation of the results. From regression coefficients and confidence intervals to interaction plots and the new contour and surface plots.

Response Surface Designs

Once you've identified the most important factors using a screening design, it's simple to fit a more detailed second-order model using our Response Surface Design procedure. The system provides Two Response panes in the analysis. It's possible to select one of four types: Surface, Contour, Square or Cube. The plots help you to determine the influence of factors on the response variable and to locate optimal regions.

Mixture Designs

The Mixture Designs procedure allows you to easily design and create an experiment to handle situations where components are mixed to form a chemical blend. You can use the simplex-lattice design, if your data values are distributed equally over a response surface region or the simplex-centroid design, if the data values are distributed around the center of the response surface region. All of the designs include linear, quadratic, special cubic, or cubic model estimations, and graphics to visualize the results.

Added in Version 4

Multilevel Factorials, Inner/Outer Arrays, Single and Multi-factor Categorical and Variance Components design classes have been added in Version 4. Plus, you will find new procedures for optimising your designs.

New for STATGRAPHICS Plus Version 5

Version 5 adds the following: new Gage Linearity and Accuracy Analysis, the Multi-Vari Charts, Life Data Regression for Reliability Analysis and Accelerated Life-Testing, long-term and short-term capability assessment estimates, plus new options for data handling in all of the control charts. There is also an enhanced General Linear Models Analysis computing expected mean squares and variance component estimates for random and mixed models. Add to this, automatic Cochrane-Orcutt and Box-Cox procedures in Multiple Regression. Levene's, Friedman's, Dixon's and Grubb's tests, Durbin-Watson P-values and bootstrap estimates in One-Variable Analysis. Increased data limits, more flexibility in naming columns, automated result saving, support for international/multi-byte character sets, enhanced 3D charts, etc.
