Wizard Pro 1.0.1

Does SPSS put you to sleep? Do you stare at the ceiling while using Stata? Does R make you go "Arrrrrgh!!"... even though you`re not a pirate?

Meet WIZARD, the user-friendly multivariate statistics program with pretty pictures and an Undo button. WIZARD takes the pain out of data analysis and lets you spend your time exploring your data -- not the vendor`s user manual. In less than an hour with WIZARD, you`ll know how to make pie charts, histograms, and scatterplots of your data, perform t-tests and analysis of variance, compute cross-tabulations and correlation coefficients, run multivariate regressions, and make concrete predictions. Doing statistics has never been easier.

Most statistics programs were designed decades ago, when computers were slow and a command line was a godsend. Today`s computers are thousands of times faster and fully graphical, but for some reason statistics programs are still stuck in the DOS age. WIZARD finally brings statistical computing into the Mac era. Say goodbye to command files and fixed-width fonts. WIZARD gives you interactive interfaces for asking questions about your data, constantly creates relevant pictures, and presents your results in the most intuitive manner you`ve ever seen. After a few hours with Wizard, you`ll achieve a level of productivity that previously required a highly-educated gang of research assistants.

But WIZARD wasn`t just designed to help you work quickly -- it`s designed to keep your work and your insights organized. Have you ever forgotten where you put a particular log file? Or the name of the spreadsheet with the back-of-the-envelope calculations? WIZARD gets rid of these problems by letting you put everything (tables, results, and predictions) into a single document, which you can email around or keep to yourself. All of your work stays visible in the iTunes-like navigator on the left, so you`ll never misplace another result again.

And have you ever wondered what the coefficients from a particular regression actually *meant*? Not only does WIZARD provide visualizations of statistical significance, but WIZARD has an innovative Predictor interface, an interactive equation that lets you see the effect of changing the predictor variables on the outcome variable. After a few seconds of playing with the Predictor, you`ll wonder what you did without it -- especially for non-linear models, where regression coefficients require context to be interpreted.

If you work with data, WIZARD is the tool you`ll wish you had years ago. WIZARD makes statistics fun again.
