Wizard - Statistics, Visualization, Data Analysis, Predictive Modeling
Mac OS Productivity
Wizard is a new Mac app that makes data analysis easier than ever. No programming, no typing — just click and explore. Wizard makes statistics accessible to beginners, but beneath the surface lies a full set of tools for doing professional research.
Featured by Apple! "New and Noteworthy" (Feb. 2013) and "Apps for Business" (Sept. 2015)
"You can be looking at statistical analyses less than a minute after importing your data." —MacFormat Magazine (UK)
It's true: within minutes of importing your first data set into Wizard, you'll be generating graphics, uncovering correlations, producing p-values, building models, and sharing insights with colleagues. Most customers find that the program pays for itself in just a few days of use. Explore Wizard's delightful feature set, including...
Wizard will start graphing your data as soon as you click on it. It uses native Mac graphics to give you crisp visual summaries — box-plots, scatterplots, histograms, survival curves, and more — in a fraction of a second.
EASY STATISTICAL MODELING
Build sophisticated statistical models in seconds with Wizard's intuitive modeling interface. Regression estimates are instantly recomputed as you play around with the controls and experiment with new specifications.
Wizard supports drag-and-drop, multi-level Undo, and other interface conveniences that Mac users expect from their software. An interactive tutorial will help you get started.
Dozens of functions are available to help you get data into the form you want. Compute quantiles, perform day-of-week calculations, multiply columns together, and more.
Export colorful graphics as web-friendly PNG or print-quality PDF. If you're surrounded by PC users, export your models as interactive spreadsheets that can be used to run "What if?" scenarios in any version of Microsoft Excel.
LIST OF STATISTICAL TESTS
Wizard supports the most common statistical tests and models, including...

LIST OF FILE FORMATS AND DATABASES
Although you have the option to enter data manually, more likely you'll want to import data from one of the following sources:
• Excel (.xls/.xlsx)
• Numbers ('09 and later)
• R workspace and single-object files (.RData and .rds)
• DBF and Microsoft Access
• Plain text (Comma-, tab-, and custom-delimited values)
To import and export other formats, including SPSS, Stata, and SAS, you can either buy In-App Purchases inside Wizard (Wizard > Unlock Pro Features...), or purchase Wizard Pro, also available in the Mac App Store. The set of included importers is the only difference between the Pro and Standard versions.
New in 1.8.12:
• New ability to rearrange columns in the Pivot view via drag-and-drop
• Switching between data tables now preserves selections in the Pivot view
• Equal-counts chi-squared test now excludes empty categories (ideal for filtering)
• Clarify in the Summary view that the t-test is Student's t-test
• Fix interface glitches in the Pivot view (including inability to delete pivots)
• Fix an occasional crash in the XLSX exporters
New in 1.8.11:
• Fix minor interface glitch in the Pivot view
• Fix occasional crash in the Model view after editing data
New in 1.8.10:
• Fix more "content is unreadable" errors in some exported Excel documents
• Fix occasional crashes with missing text values present
New in 1.8.9:
• Fix "content is unreadable" errors in some exported Excel documents
• Fix an occasional crash in the Pivot view after an Undo
• Fix minor interface glitches in the Raw Data and Pivot views
New in 1.8.8:
• "Export as XLS" menu items have been replaced with "Export as Excel". In the majority of cases these files will now be exported in the XLSX format, rather than the older XLS format. This fixes issues with exported data tables and correlation matrices exceeding the size limitations of the XLS format.
• Many cosmetic improvements to exported Excel files
• Fix an interface glitch with the "Count" column in the Summary view
• Fix a crash associated with missing text values
New in 1.8.7:
• Fix a crash when editing column descriptions with a name filter applied
New in 1.8:
• REFRESH FROM WEB: Ever wish you could grab data directly from the web? Now you can import files directly from the WWW just by clicking "Import URL" and typing in a web address. Wizard will download the file for you, and keep your analysis up-to-date every time you click the "Refresh Data" button. The new feature is ideal for JSON data, but is designed to work with every file format supported by Wizard.
To get started, choose File > Open URL, or click the new "Import URL" button in the toolbar.
• POST-HOC ANALYSIS: A.k.a., "multiple comparisons corrections". If you're hunting for significant p-values, you should usually apply a statistical correction to account for the number of simultaneous tests you're performing -- this keeps your Type I error rate under control (and also keeps the journal referees happy). Now applying the correction is as simple as checking the box labeled "Adjust for multiple comparisons" and entering a number. To avoid confusion, corrected p-values will appear with an asterisk.
(The applied correction is technically a Šidák correction, which is slightly more accurate than Bonferroni. You are nonetheless encouraged to celebrate the new feature by belting out "Bonferroni" to the tune of "My Sharona".)
• NEW TEXT FUNCTIONS: "Concatenate" joins together multiple text columns with an optional separator. "Convert to Numeric" changes the underlying storage of a text column to be numeric. "Count Characters" and "Count Words" lets you compute the lengths of text values, ideal for analyzing natural-language data.
If you'd like more text functions, just send me an email with your request and I'll take it under consideration. (Choose "Email the Developer" from the Help menu.)
• MISCELLANEOUS IMPROVEMENTS: The Raw Data and Pivot views now remember each column's width when you resize it. (Less "resize hell" after re-opening a document.) The Column menu has been cleaned up to display only functions that are relevant to the selected column. The Pivot view allows you to perform "Count Non-missing" on a category column. The "Enter Full Screen" shortcut is now the same as Apple programs (Control-Command-F).
Note that Wizard now requires OS X 10.9 or later. If you are running an older operating system, please take time to upgrade your system.
Enjoy the new features!
