Matrix Package Doodling

bounded normal mean
A few days ago, one of my students, Jacopo Primavera (from La Sapienza, Roma) presented his “reading the classic” paper, namely the terrific bounded normal mean paper by my friends George Casella and Bill Strawderman (1981, Annals of Statistics). Even though I knew this paper quite well, having read (and studied) it myself many times, 
A Function for Adding up Matrices with Different Dimensions
I was unlucky finding a function that can handle matrices with different dimensions. Thus, I coded a little function that sums up matrices, also coping with matrices with different dimensions.Read more »
Book shoppin’…
I honestly have no book on R programming. In fact I have not a single book on programming at all (my coding proves that ;x). I am pretty sure that I am gonna order (just did!) that book. You can get a look of Matloff’s text here (= pdf for ya)
Bringing 64-bit data to R
The R programming language has become one of the standard tools for statistical data analysis and visualization, and is widely used by Google and many others. The language includes extensive support for working with vectors of integers, numerics (doubles), and many other types, but has lacked support for 64-bit integers. ...
“Home Runs by Park – 2011 Season” or “Man the Astros Sucked This Year”
I hate the Giants. Let this be known. What i was hoping to find was another reason to support my claim that their WS win in 2010 was a complete fluke. So when digging through the game logs for the … Continue reading →

Empirical Orthogonal Function (EOF) Analysis for gappy data
The following is a function for the calculation of Empirical Orthogonal Functions (EOF). For those coming from a more biologically-oriented background and are familiar with Principal Component Analysis (PCA), the methods are similar. In the climate sciences the method is usually used for the decomposition of a data field into dominant spatial-temporal modes.
