"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...

QUICK VISUALIZATIONS

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.

MAC FRIENDLINESS

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.

DATA TRANSFORMATIONS

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 EXCELLENCE

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 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:

File Formats
• Excel (.xls/.xlsx)
• Numbers ('09 and later)
• R workspace and single-object files (.RData and .rds)
• JSON
• SQLite
• DBF and Microsoft Access
• Plain text (Comma-, tab-, and custom-delimited values)

Database Servers
• MySQL
• PostgreSQL

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.

What's New in Version 1.8.16

New in 1.8.16:

• Fix inability to select "Any" condition when censoring a survival time
• Fix interface glitch in the Model view
• New support for exporting long strings to SPSS binary format [Feature requires In-App Purchase]
• Improved support for reading long strings from Stata binary format [Feature requires In-App Purchase]


New in 1.8.15:

• Improved exporting to Stata binary format. New support for exporting long strings and Unicode text [Feature requires In-App Purchase]
• Improved importing of SPPS portable files [Feature Requires In-App Purchase]
• Fix a rare crash when processing non-UTF-8 text data


New in 1.8.14:

• Fix ability to edit names of Filter Sets
• Fix occasional crash after duplicating a table
• Fix instabilities after importing extremely large numbers
• Fix scrolling glitch in the Summary view with multiple columns selected


New in 1.8.13:

• Improved support for reading Stata files with a row limit applied [Feature requires In-App Purchase]
• Improved support for reading compressed SAS files [Feature requires In-App Purchase]
• Improved support for writing SPSS files [Feature requires In-App Purchase]
• Fix an interface glitch when switching between pivots
• Fix an occasional crash when duplicating a table
• Fix an occasional crash after Undo
• Fix an occasional crash when exporting XLSX


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!
