Very helpful course, I highly recommend it. If nothing else, get a copy of the book:<p><a href="http:&#x2F;&#x2F;www-bcf.usc.edu&#x2F;~gareth&#x2F;ISL&#x2F;ISLR%20Fourth%20Printing.pdf" rel="nofollow">http:&#x2F;&#x2F;www-bcf.usc.edu&#x2F;~gareth&#x2F;ISL&#x2F;ISLR%20Fourth%20Printing....</a><p>Even though the book is introductory material, it explains everything with great clarity. I have yet to find a better resource for someone wanting to get into data science. The theoretical material side-by-side with coded examples is very powerful (although the labs could use some work). Even if you have been using data science for a while, this is a great refresher on theoretical concepts.
