Bond Shop Views with dimplejs and rCharts

14.03.2014

I saw this chart in a presentation and thought I could make it better and interactive.  Here is a short article on the iteration process.  Click on the screenshot below or here for the full post. Note: these are not my views and this is not financial advice.  I did not name the original source of the graphic.  If you are the sourc...

Help Me Understand bfast breakpoints

20.03.2014

The R package bfast enthralls me.  I have posted 3 times on bfast but still did not understand the impact of the h parameter.  Armed now with some d3.js, angular.js, and rCharts I thought I could see it better with a fancy interactive visualization.  Here is the result when applied to the S&P 500 monthly price series since 1950.  ...

Interactive Discovery of Research Affiliates JoPM Paper

25.03.2014

In my previous post More on Rebalancing | With Data from Research Affiliates , I did some really basic visualizations, but I thought this data would be great for some more powerful interactive discovery using an interesting javascript SQL-like query language objeq along with the d3.js charting library dimple.js.  Next, I hope to ext...

R as a Publishing Engine | CPI Components Use Case

04.04.2014

R was certainly not designed to be a publishing engine, but in my workflow, R is the primary method of content creation.  With that in mind, I have been thinking about a very different use case of rCharts in which we might want to include inflexible and not really reusable custom javascript components in our document.  As a quick ex...

Find it Humorous … “Not So Bad” in the “long-term”

11.04.2014

I agree the market selloff has been weak thus far (especially as a frustrated bear).  However, I find it humorous as some widely followed commentators say things like “You’re only down x% ytd.  It’s not that bad”.  I wonder if this selloff gets worse will they extend to a 12 month horizon since last year was so good.  Imme...
