Expert guidance in analyzing your research

SigmaStat's Advisor Wizard asks a series of simple questions and recommends the best test to run.
SigmaStat ensures that you:

Use the proper statistical method to analyze your data
Avoid the risk of statistical error
Interpret the results correctly
Generate an appropriate display and a professional report
Be sure you've analyzed your data correctly. And save time, too!

SigmaStat features make analysis fast and easy
The Advisor Wizard guides you in correctly analyzing your research findings. It:

Asks a few basic questions about your research
Suggests the appropriate statistical test

Ifyour data violates the recommended test's underlying assumptions,SigmaStat warns you of this, and suggests a more appropriate test.

Then SigmaStat:

Checks your data against the test's underlying assumptions
Suggests another test, if your data violates any of original test's assumptions
Provides a report interpreting the results, in terms you can understand

SigmaStat Report Editor

Youcan navigate through this report, and then edit and print it just asyou do any document created with word processing software.

The SigmaStat report helps you interpret results.

New features in SigmaStat 3.0

Access to SigmaPlot
Survival analysis
New report page
New data worksheet
Graphing improvements
Support for Microsoft® Windows® 2000 and Windows XP
And more…

AccessSigmaPlot from SigmaStat's Graph menu, and then use SigmaPlot's Pagetoolbar to edit multiple items simultaneously or to selectively editindividual bars, lines or points.

Access to SigmaPlot
Nowyou can open your SigmaPlot files in SigmaStat to test additionalhypotheses. Share files between the two programs to avoid the confusionof having multiple files with the same data. And use SigmaPlot'sediting tools, such as the Graph Properties dialog, tool palettes andtext toolbar, to change any detail of your graphs - all from withinSigmaStat.

Open SigmaPlot files in SigmaStat 3.0
Open SigmaStat files in SigmaPlot (requires SigmaPlot 8.02)
AccessSigmaPlot's toolbar editing palettes, text toolbar or Graph propertiesdialog to customize SigmaStat graphs (requires SigmaPlot 8.02)

Comparesurvival rates among groups, and then display survival curves the wayyou prefer. Add error bars or confidence intervals, display of censoredor failure values, define the survival scale as percent or fraction,and differentiate with color.

Survival analysis
Predictingsurvival or reliability rates is difficult when you don't know thefinal outcome for every subject. Now it's easier, because SigmaStat 3.0includes the Kaplan-Meier (product limit) method to estimate thesurvival function of cases followed over time. You can compare survivalrates among groups, using SigmaStat's robust multiple comparison tests.And display the results just as you like, thanks to a variety ofsurvival curve options, including error bars and confidence intervals.

Use Kaplan-Meier (product limit) estimation method
Compare results for single or multiple groups
Perform multiple comparison tests, including Holm-Sidak
Analyze data in either raw format (one group per column) or indexed data (all groups in a single column)
Choosesurvival curve options: show error bars or confidence intervals,display censored values, define the survival scale as percent orfraction, and differentiate groups with color

New report page
Nowyou can navigate through your entire report document by using scrollbars or keyboard commands, just as you do in popular word processingprograms. Share your data with colleagues over the Web or by e-mail, byusing PDF and HTML export options. Copy graphs to your report andpreview the report before printing.

Export reports to both PDF and HTML formats
Use familiar keystroke commands to move through a report and select text
Add decimal tabs and margin controls more easily with improved formatting ruler
Preview report before printing
Edit your report efficiently with new "multiple undo" option

Formatcells to display integers and decimal values in the same worksheet. Addrow titles, use long text strings for column headings or worksheetcells, adjust the row or column sizes. Select a point or group on yourgraph, such as an outlier, and the corresponding cell, column or row ishighlighted in the worksheet.

New data worksheet
Thenew SigmaStat worksheet contains 32 million rows and 32,000 columns, tokeep pace with the increasing volume of data you collect. You can moveto the end of columns or rows with the same keyboard commands that youuse in familiar spreadsheet programs, allowing you to keep your handson the keyboard when entering data. Format both columns and individualcells to display each type of data in an appropriate format, allowingyou to use integers and decimal values in the same worksheet.

Load data into as many as 32 million rows and 32,000 columns
Use familiar keystroke commands to move through the worksheet and select cells
Format individual worksheet cells and columns
Adjust row and column sizes
Add row titles
Use longer text strings and variable names in row and column headings

Edit your worksheet efficiently with new "multiple undo" option

Graphing improvements
Oneof the chief benefits of SigmaStat is that it enables you to performstatistical analyses without rearranging your data. Now this is true ofSigmaStat graphing, too. With the improved Graph Wizard, you can chosefrom multiple data format options or graph a selected portion of yourdata. By recalling previous graphing selections, the Graph Wizardenables you to efficiently create multiple graphs from the sameworksheet simply by inputting the information that changes from one tothe next.

Use the improved Graph Wizard t
Create graphs from data in various formats - such as XY pair, single Y/X, multiple X/Y, and more
Select a range of rows from a column
Recall previous selections
Position objects precisely by using new grid lines and "snap-to" options
Hold graphs at a preferred viewing size, by setting a default zoom level
Insert graph legends automatically
Incorporate additional symbol types
Edit graphs efficiently with "multiple undo" option
