A review of Wizard Pro
When I first started the list of data analysis packages for Mac OS X it was a fairly short list, over the years the list has grown and the diversity of packages increased. From free packages like R to enterprise applications like IBM SPSS costing thousands. Some packages are enormously powerful but have a ferocious learning curve, whilst others are very easy to use but have only very limited capabilities. Wizard is an intuitive data analysis tool, designed from the ground up to be readily accessible but still retain the power of the sophisticated command line driven applications that only seem suitable for programmers. Wizard Pro allows the user to explore the data interactively without the need to learn a programming language. Read more here.
I should have added Wizard Pro runs under Yosemite and is on the list of Yosemite compatible applications, and has just been updated to version 1.6.7 (Feb 27th).
