Network analysis with igraph

Suddenly, I had to learn network analysis. Two weeks ago I started with a book by Christakis and Fowler, then a book by Kolaczyk and Csárdi, now here I am in a “how to” analyse network data using R moment.

Randomized Hobbit

@wrathematics pointed me to his ngram R package for constructing and simulating from n-grams from text. I’d recently grabbed the text of the hobbit, and so I applied it to that text, with amusing results. Here’s the code I used to grab the text. Then calculate the ngrams with n=2. Simulate some number of words […]

dynamic mixtures [at NBBC15]

A funny coincidence: as I was sitting next to Arnoldo Frigessi at the NBBC15 conference, I came upon a new question on Cross Validated about a dynamic mixture model he had developed in 2002 with Olga Haug and Håvård Rue [whom I also saw last week in Valencià]. The dynamic mixture model they proposed replaces […]
