StatET IDE for R

I personally do not use Integrated Development environments (IDEs) for R, or for that matter for any programming language. From my point of view, they take up too much precious real estate on the screen, and most important, they generally do not allow me to use my own text editor and my own abbreviations and … Continue...

New Release of partools Package

My new release of partools is now on CRAN. The package is aimed at doing parallel data science in what I call an “un-MapReduce” manner. It takes the point of view that MapReduce-based frameworks such as Hadoop and Spark are fine for the types of applications their designers had in mind, namely rather simple SQL … Continue...

Bad Coder, Bad Coder!

Bad Coder, Bad Coder!

My title here is in the sense of “Bad dog, bad dog!”, a scolding I sometimes see dog owners use to tame their pets, and is also an allusion to Bad Reporter, a sometimes hilarious and always irreverent political comic strip in the San Francisco Chronicle. And my title is intended to convey the point … Continue reading...

Latest on the Julia Language (vs. R)

I’ve written before about the Julia language. As someone who is very active in the R community, I am biased of course, and have been (and remain) a skeptic about Julia. But I would like to report on a wonderful talk I attended today at Stanford. To my surprise and delight, the speaker, Viral Shah of Julia … Continue reading...

Talk on regtools and P-Values

I’m deeply greatful to Hui Lin and the inimitable Yihui Xie for arranging for me to give a “virtual seminar talk” to the Central Iowa R Users Group. You can view my talk, including an interesting Q&A session, online. (The actual start is at 0:34.) There are two separate topics, my regtools package (related to … Continue reading...

The main topic will be usage of GPU in conjunction with R, and I will also speak on my Software Alchemy method, especially in relation to GPU computing.. GTC asked me to notify my “network” about the event, and this … Continue reading...

Even Businessweek Is Talking about P-Values

The March 28 issue of Bloomberg Businessweek has a rather good summary of the problems of p-values, even recommending the use of confidence intervals and — wonder of wonders — “ at the evidence as a whole.” What, statistics can’t make our decisions for us?  :-) It does make some vague and sometimes puzzling statements, … Continue reading...

P-values: the Continuing Saga

I highly recommend the blog post by Yoav Benjamini and Tal Galili in defense of (carefully used) p-values. I disagree with much of it, but the exposition is very clear, and there is a nice guide to relevant R tools, including for simultaneous inference, a field in which Yoav is one of the most prominent, … Continue reading...

Further Comments on the ASA Manifesto

On Tuesday I commented here on the ASA (in their words) “Position on p-values:  context, process, and purpose.” A number of readers replied, some of them positive, some mistakenly thinking I don’t think statistical inferences are needed, and some claiming I overinterpreted the ASA’s statement. I’ll respond in the current post, and will devote most … Continue reading...
