"You can be looking at statistical analyses less than a minute after importing your data." —MacFormat Magazine (UK)
Do you like learning from data? Are you frustrated that all statistics programs are still stuck in the 1980s? Wizard is a 21st century statistics program designed to make data analysis fun, enjoyable, and highly productive.
Like a friendly college professor, Wizard makes statistics accessible to beginners, but beneath the surface lies a full set of tools for doing professional research. Within minutes of opening the program for the first time, you'll be generating graphics, uncovering correlations, producing p-values, 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, 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. They'll wonder how you did it.

LIST OF FILE FORMATS
You can import and export any of the formats listed below (or enter data manually). So besides being a full-featured statistical package, Wizard works as a handy tool for converting files.
+ Excel/Numbers (.xls/.xlsx/.numbers)
+ R workspace files (.RData)

+ Tab-delimited (.tsv and .tab)
+ Text files with custom field delimiters
+ Excel (.xls)
+ R workspace files (.RData)
+ Comma-separated values (.csv)
To import and export other files, including SPSS, Stata, and SAS formats, you'll need Wizard Pro — also available on the Mac App Store. This is the only difference between the Pro and Standard versions.

* Preserve filter selections when switching between tables
* Correctly parse numbers surrounded by spaces in CSV files
* Fix a bug where a blank header cell in an Excel spreadsheet caused subsequent columns not to be imported
* Fix some issues with PDF export of model images
* Fix a crash when stacking tables with indicator variables
New in 1.3.1:
* NEW copy images directly to clipboard
* Fix a bug where date columns were not always recognized when importing XLSX
* Fix a crash in the Raw Data view
New in 1.3.0:
NEW! Features for working with R — the popular statistical computing package — have graduated from Wizard Pro and are now available in regular Wizard. Import and export R workspace files (.RData), and easily copy models as R code (in the Model view, just choose View > Show Estimation Command). If you've ever been interested in R but felt lost on the command line, Wizard will be your trusted companion.
...but wait, there's more! I listened to your feedback and have addressed the Most Popular Feature Request: importing newer Excel files (the XLSX file format). Wizard can now read in XLSX with ease. So if you see any old reviews bemoaning the lack of XLSX support, please note that as of today they are 100% obsolete. Being able to import XLSX is ideal for people who work with large data sets, as the older XLS format cannot store more than 65,000 rows.
...but that's not all! To make up for several months of missing XLSX support, I went the extra mile with Wizard 1.3 and implemented the ability to import Numbers spreadsheets, that is, files ending in ".numbers". If you choose File > Import Numbers Document, Wizard will scan your spreadsheet and suck in all the data tables that it can find. So if you're a Numbers fan like me, now you can import your data into Wizard without having to export it as XLS first.
...but it gets even better! Update Wizard in the next 20 minutes and you'll get the following excellent bug fixes absolutely free of charge:
* Fix a crash when zero observations are included in the Model view
* Fix a bug when importing multiple sheets in XLS documents
* Fix a bug where Q-Q plots were not properly exported as PDF
