"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.

New in 1.9.12:

• Multinomial logit models: Fewer "Not enough data" errors when the outcome distribution is heavily lopsided.

• Multinomial logit models: Fix a bug in the Predict view when one or more outcome values are filtered out. (Previously, the Predict view would assign positive probability to filtered-out values.)

• Ordered probit models: Fix a bug in the exported XLS file when one or more outcome values are filtered out. (Previously, Excel would report an error about corrupt or missing data.)


New in 1.9.11:

• Improved navigation of topics in the Help file
• Fix formatting of mean values in the Summary view for durations, currency, etc.


New in 1.9.10:

• Fixed a number of broken links in the Help file
• Fixed an interface glitch viewing Predictions after opening a saved file
• Fixed an interface glitch viewing correlation tests when correlation=1
• Improved ability to cancel MySQL operations


New in 1.9.9:

• Database importers: Increase timeout to 3 minutes
• MySQL importer: Fix bug when importing NULL numeric values


New in 1.9.8:

• Added support for computing Spearman's rank correlation coefficient
• Correlation tests now display the correlation coefficient rather than the z-score
• Improved performance of Standardized columns
• Improved support for importing POR files [Feature requires In-App Purchase]


New in 1.9.7:

• Display the correct number of decimal places in the Filters pane
• Improved support for importing R workspaces


New in 1.9.6:

New in 1.9.5:

• Fix a bug where standard errors in the Summary view did not display the correct number of decimal digits
• Fix a bug where empty sheets in Excel files caused importing to fail
• Fix a number of uncommon crash issues


New in 1.9.4:

• Improved compatibility with SAV files when IBM SPSS Statistics is installed on the same machine


New in 1.9.3:

• Improved support for importing Numbers files
• Fix a bug parsing 24-hour times in CSV files

New in Wizard 1.9:

FROM THE LOWER DEPTHS OF HELL comes Wizard 1.9, a malign masquerade ball of new features and functionality. If you thought that Wizard could already do everything when it comes to data transformation and analysis, YOU WERE WRONG. In the biggest release since last year's sleeper hit Wizard 1.8, Wizard 1.9 brings you...

* COLLAPSIBLE FILTERS -- Make the most of screen real estate with the new Pin button -- when activated, it keeps filters applied even when you close the Filters pane.

* DATES, DATES, DATES -- Import dates in your favorite format, format your dates with four exciting date templates, analyze dates with down-to-the-second precision, partition date/time data with greater flexibility, and create Timestamp columns using the number of seconds from a particular start date.

* FILE SIZE FORMATTING -- Does your data set include a file size measured in bytes? Now you can format it with easy-to-read units (KB, MB, GB, etc). There's even an option to switch between the decimal convention (1,000 bytes per kilobyte) and the binary convention (1,024 bytes per kilobyte).

* NEW PIVOT FUNCTIONS -- Standard Error of the Mean and 95% Confidence Interval, now available for your pivoting pleasure.

* ITUNES IMPORTER -- Automatically pull in your music collection and see all the new features in action with the new iTunes importer. Visualize your listening habits by time of day, tally up your music collection by artist and genre, and graph file sizes and track lengths just for kicks. To get started, use the new menu item File > Import iTunes Music Library...

These are just the big-ticket items -- in addition, Wizard 1.9 boasts countless interface tweaks and bug fixes to make your statistical experience as smooth, seamless, and streamlined as possible. Enjoy it on OS X 10.10 (Yosemite) or later.

Review by pjn.

Pretty close to perfection - I do a fair amount of data analysis - in filemaker, excel and occasionally in R. R is fabulous (almost infinite numbers of tools), but the learning curve is steep to put it mildly. Excel and filemaker are what they are. This program is all I could dream for and will likely be my main number analysis application - for my purposes, CSV / excel import is all I really need, so the Pro version would likely be overkill. I am just bowled over by how easy it is to use and how well thought out it is. And how pretty it is - but this doesn't come at the cost of power. And the user interface has been customized to suggest what you should do - for example an "open file" dialog box prompts you as to what sort of files you can import and, most importantly, how the data in them should be arranged. I think this is my "best app for 2012" winner!

Version 1.9.5
Review by kelohedeb

App Cannot Print! - There is no “Print” functionality in this app for pivot tables. No “Print” menu item. No “Print” button. No help or documentation on how to print anything, including pivot tables. I set up some basic stats using imported data and then spent HOURS trying to figure out how to print it. There’s no email support, only a google “support” group. I joined, searched for “print”, and then slogged though posts looking for an answer. When I couldn’t find anything helpful, I posted a query asking how to print. A day later, the developer responded. The short answer is: “You can’t.” Here’s what he said: "The easiest way to print your Pivot table is to export to Excel (menu item Pivot > Export Pivot Table as Excel...) and print from Excel or Numbers -- the formatting will be preserved, and these programs offer extensive printing options.” The app costs $80+ and the only way to print a pivot table is to export your data to Excel? This could be the world’s greatest data analysis app, but I wouldn’t know. I’m in the process of getting a refund.
