Created by Dr. Shidan Murphy, an award-winning scientist and educator, R Instructor allows you to run RStudio through a public web server from your phone or tablet (Internet connection required -- do not expect a super computer -- this server is for for experimenting with your scripts) and teaches R using plain, non-technical language and over 30 videos. The number and scope of the videos and content will continue to increase.
R Instructor will teach you how to use R, how to make and modify plots and run statistical tests. Each example includes a very brief (and easy to understand!) description of the function or test, any statistical assumptions, how to structure your data in R, the R scripts (code) and, links to other free and online resources.
Where appropriate, the Mac, Windows and RStudio versions of the R interface are explained separately.
** As an added bonus – If you don't know the statistical test you need, use the included "Which test?" feature! Just answer the questions about your data. **

Think about this for a second – when you imagine a perfect online learning platform what do you want?
If you are new to the subject, you want a customized learning road map written by a subject matter expert. Someone who knows exactly what you need to understand and pick up and can help you navigate the hurdles of learning a difficult concept.
You don’t just want online HTML based content. Ideally it would help if you have a few videos, some take home PDF files that you can download and read at your pace on the train or at the airport and it would be really neat if somehow there were at least a few excel templates that can help you walk through what you have just covered.
Lets see how we stack up against that online education check list
• Custom learning road map – check
• Online HTML content – check
• Online Videos lectures - check
• Downloadable PDF files – check
• Excel templates – check
• Videos about building excel templates – check
As a student every once in a while you want to walk away from the learning plan and explore what else is out there. Yes you can do that here. We cover topics of interest and what is happening in markets and you can see that on the recent post tab. If you want to do something completely different like brushing up on correlations or asset liability management, you can do that too by walking through our list of 40 plus active courses.
Then there is the academic piece. Two Fellow society of actuaries, one Columbia Business School MBA, three published text books and a highly rated Executive MBA faculty member described as “one of the best unconventional Executive MBA finance professors on campus”.

Want to learn "how to program" ? Algoid is made for you !
Algoid is an educational application for Android that teaches kids, teenagers and why not their parents "how to program".
★★★ With Algoid, learn programming become simple and funny !
Do you remember the Logo programming language ? This friendly turtle / robot that introduces step by step the basics of programming.
Algoid is based on the same idea of visual feedback loop : develop - run / debug - observe turtle that draw result.
★★★ Algoid go further, it embeds a real-time DEBUGGER (the first and so far the only one on Android), a step by step execution mode and SCOPE EXPLORER (for better understanding).
Still further, hide the turtle and develop your own VIDEO GAME directly from your device.
In short, Algoid will turn your Android device into a real development station dedicated to apprenticeship and fun.
Everything you need to become a future developer, whether you are a child, teenager or adult!
The goal of Algoid is to enable everyone to "learn to program" or "learn programming".
---- Highlights ----
Algoid is an all in one app that embeds tree products :
The rich integrated development environment "IDE" :
- Syntax highlighting
- BREAKPOINTS and DEBUGGER
- STEP BY STEP execution modes
- real-time SCOPE EXPLORER
- Auto completion
- Syntax error management
- Unlimited Undo/Redo
- UI optimized for small screens
The documentation platform for self apprenticeship
- Online forum
---- What's algoid is not ? ----
Algoid is not running through SL4A, it integrates its own (homemade) formal language parser. This choice was made to facilitate the debugger, step by step and scope explorer integration.
Its language AL is not Java, but its interpreter and runtime are both written in Java.
Algoid is not a compiler but a scripting language interpreter.
Algoid is not (not yet but I am working on) a c or java ide but a dedicated one for AL.
NOTE: The complete app can be now downloaded from the same user with both Quant and Verbal questions at a fee of just $2.
