I Just Completed 100 Tableau and Alteryx Focused Blog Posts

Introduction

I've been writing a Tableau and Alteryx-focused blog for 1.5 years on Wordpress and haven't thought of writing anything here on DSC. I just completed a two-part series that discusses solving problems using innovative approaches with Alteryx and Tableau, which were my 99th and 100th blog posts. They are longer than usual but offer a good insight into my background and why I write a technical blog.

My blog is focused…

Do you know what is bigger than Big Data?

From episode 10 of my Naked Analyst Channel on YouTube.

I think I do - and it is the ‘appification’ of analytics. What I mean by this is the reduction of a complex analytic activity such as market segmentation, down to a single button on your computer interface. Very much like the…

Clustering Similar Images Using MapReduce Style Feature Extraction with C# and R

Abstract

R as Ad Hoc

I was reading through my Twitter feed the other day and saw a comment about the R language being too ad hoc for users.  It got me thinking, "Is that bad? Aren't most languages initially seen as ad hoc?".  

The beauty of R as a data science tool is its "ad hocedness" in that its use can satisfy multiple interests.  Initially I can see this as troublesome in that learning the specificity of a tool's use can be daunting.  But in the long-run I think this benefits a…

SAS Dominates Analytics Job Market?

Bob Muenchen's very useful work on this topic, SAS Dominates Analytics Job Market; R up 42% sent me back to some 2012 work we did at Statistics.com on the subject of what employers are looking for in the way of analytics skills.  First, our main results:

1.  Our numbers showed a much less SAS-dominant world:  1.92 SAS jobs for every R job.  Bob had found the ratio to…

Automatically deskew before machine learning in R

I found it odd there was no way to automatically deskew data in R, so I wrote a short little function to do it.  It noticeably improves the peformance of linear models and linear support vector machines.

The Fallacy of the Data Scientist Shortage

There is no question that the USA (in fact, most of the world) would be well-served with more quantitatively capable people to work in business and government. However, the current hysteria over the shortage of data scientists is overblown. To illustrate why, I am going to use an example from air travel.

On a recent trip from Santa Fe, NM to Phoenix, AZ, I tracked the various times:
