Data Science From Coursera.org and Johns Hopkins


Always learning! Enrolled today in what may be the single best online Data Science course anywhere. ...Offered through www.Coursera.org & Johns Hopkins Univ. #data #rstats #Analytics

Have done a bit of work already with R (including "Beginning R for Excel Users" on LinkedIn), and since it's the best language for data/statistics analysis. But, this course offers a comprehensive overall framework that can be practically applied to other life science applications, social science, and yes, the wonderful world of business analytics.

Sidenote1:  It seems like all the latest business intelligence applications have in-memory analysis, dimensional analysis, and tools that are similar, or follow similar methodology to R. ...This includes Tableau, Microsoft's DAX, and (my preference), QlikView & Qlik Sense.

Sidenote2:  Graph below was my first R visualization a few months ago, showing in just a few lines of code, a comparison bar chart of recent train station renovations here with Chicago's CTA (the "L").  ...Let's see if there's even better to come!
