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" (Apr. 2013)
"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 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.
