I’m delighted to report DataDesk 7 has been released, this update requires a Macintosh computer running Mac OS X 10.6, 10.7, 10.8, or 10.9 and Intel processor and 2 GB RAM.
Data Desk brings fast, easy-to-use visual analysis to your desktop. It provides interactive graphical tools for exploring and understanding your data—for finding the patterns, relationships, and exceptions. While it implements many traditional statistics techniques suitable for data from planned experiments and sample surveys, Data Desk’s true strength is its powerful tools for data exploration. Its insightful graphic displays simplify intuitive investigation of your data.
DataDesk can handle very large datasets (up to 2 billion cases), it supports a wide variety of statistical techniques and supports linked plots so that selections in one plot are highlighted in another so you get multiple views of your data. They have supported the Mac since the mid 1980’s and I suspect it is now the oldest commercial application for the Mac. A series of continuous updates have kept DataDesk at the forefront of data analysis. The accompanying manual also serves as an invaluable resource for learning statistical analysis.
I’ve updated the list of data analysis tools available for the Mac.
I’ve been asked a couple of times what application I use to create screen capture movies, I actually use Screenflow and I’d certainly recommend it to anyone who is planning create regular screen recordings. However if it is a one off movie than you can use QuickTime Player, go to the File menu and select “New Screen Recording”.
A small widget appears that offers a couple of options and is used to start the recording.
Once finished stop the recording and you can use Quicktime to do any minor edits or you can use iMovie to do more substantial editing.
I was recently sent a link to an interesting publication.
As someone who has known a number of MS patients I was very much aware of the difficulties in accurately assessing the progress of the disease. The MSPT application uses the iPad as a data collection platform to assess balance, walking speed, manual dexterity, visual function, and cognition. It also provides an objective analysis and comparison with a reference population.
Calca is a powerful symbolic calculator that updates as you type giving you instant answers. It solves equations and simplifies complex expressions. It's also a rich Markdown text editor so that you can explain your ideas alongside your calculations. This looks like a really interesting application,
x = 42
f(c) = 9/5*c + 32and even recursive functions
- Units 42 mph in kmph and currency ¥599 in $
- Solves equations (
x + 2x + 4x = 42, what is x?)
- Matrices with inverses so you can solve linear equations
- Sum, prod, map, and reduce operations on lists, matrices, and ranges
- Trigonometry and complex numbers
- Derivatives of functions
- Logic operations and if statements
- Binary math (& and |) and support for binary and hex number (
- Keeps track of units (m, s, m/s, m/s^2, etc.) so you can verify your equations as you compute
There is a comprehensive reference page that gives more details.
The nice thing is you can use Markdown to format the calculation and add an explanation.
There is a listing of Markdown Editors for Mac OSX here,
X11 2.7.7 has been released
The XQuartz project is an open-source effort to develop a version of the X.org X Window System that runs on OS X. Together with supporting libraries and applications, it forms the X11.app that Apple has shipped with OS X since version 10.5.
Download XQuartz-2.7.7_rc1.dmg, and open it with OS X's Installer.
OS X Requirements
OS X 10.6.3 or later is required to install this package.
Default X11 Server
If this is your first time installing XQuartz, you may wish to logout and log back in. This will update your DISPLAY environment variable to point to XQuartz.app rather than X11.app. If you would prefer to keep using X11.app as your default server (you can still launch XQuartz.app manually), you'll want to disable /Library/LaunchAgents/org.macosforge.xquartz.startx.plist using launchctl(1).
