Data Mining and Predictive Analytics: 6 Reasons You Hired the Wrong Data Miner

A Compilation on Time Series and Stochastic Processes geared towards Quantitative Finance

Beware - this is NOT an original piece of work!

I just prepared a compilation from Wikipedia articles and repackaged it into a pdf file. I will later try to repackage it into Kindle format using Caliber. I couldn´t get to upload it to my own site, so I am sending it to Slideshare so you can download it.



It amounts to a LARGE file, almost 200 pages long, so think before you print...

The idea was to put everything together (or almost everything...) in a halfway cohesive manner, to serve as an off-line and free reference for those interested in Time Series, Stochastic Processes and Quant Finance.

Once again, I am NOT responsible for the content, I just compiled it from Wikipedia in English.

Free online courses in stat and data mining - Coursera

I discovered by chance a website that I thought was absolutely wonderful, with sensational and free courses taught by professors from major universities (so far I only noticed universities in the USA).

It looks so good that I signed up for three courses. Now I have no excuses not to learn R.

The link to the homepage is: https://www.coursera.org/courses

I was looking for courses related to Statistics and Data Mining, and found things that seemed wonderful. If you want to start where I began , see : https://www.coursera.org/category/stats.
