A Visual Explanation of OLS Regression

Also, if you&#x27;re in SF and are interested in learning more about d3.js, one of the primary libraries that we used to build EV, we&#x27;ll be teaching a 1 day workshop May 2nd geared towards people comfortable with data but haven&#x27;t gotten deep into web programming. We&#x27;ll also be using &quot;explorable explanation&quot; style techniques along the way.<p>Have a look at our preliminary workshop demos for an example: <a href="https:&#x2F;&#x2F;vicapow.github.io&#x2F;d3-1-day-workshop&#x2F;" rel="nofollow">https:&#x2F;&#x2F;vicapow.github.io&#x2F;d3-1-day-workshop&#x2F;</a><p>I promise the demos will get more advanced and start incorporating data before the workshop :)<p>You can apply to the workshop here: <a href="https:&#x2F;&#x2F;docs.google.com&#x2F;forms&#x2F;d&#x2F;1VgBUu7znZVllkVw2d6TISzsTjGDDviPF3vbo-Zlz6ME&#x2F;viewform" rel="nofollow">https:&#x2F;&#x2F;docs.google.com&#x2F;forms&#x2F;d&#x2F;1VgBUu7znZVllkVw2d6TISzsTjGD...</a><p>The application process is to ensure everyone&#x27;s at about the same level. If you&#x27;re accepted, the ticket is $99 and includes food and refreshments.

Great visualization (as the rest from <a href="http:&#x2F;&#x2F;setosa.io" rel="nofollow">http:&#x2F;&#x2F;setosa.io</a> , go have a look)!!<p>I wonder, though: I learnt OLS as standard math &#x2F; symbolic logic; but, if kids and students learnt from these visualization, would they be better off, or worse off?<p>Because, at least for me, it is difficult to reason about this and other visual math examples (whereas there are others that are great as demonstrations, as the integer proof in <a href="http:&#x2F;&#x2F;www.catonmat.net&#x2F;blog&#x2F;visual-math-friday&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.catonmat.net&#x2F;blog&#x2F;visual-math-friday&#x2F;</a> , this one, regarding OLS, <i>confuses</i> me).<p>It probably depends a lot on each person. Out of curiosity, does this particular example give you insights? Which ones? How?

love it. a cool feature for the visualizations after the first would be to show the SSE for the OLS line vs whatever configuration you picked.
