After last week's post it was commented that strucchange and segmented would be more suitable for my purpose. I had a look at both. Strucchange can find a jump in a time series, which was what I was looking for. In contrast segmented is more suitable f...
The other day I saw a plot with some data with a clear jump in it. So I wondered if it were possible to determine the position of that jump. Data with a jump is easy enough made:library(ggplot2)n <- 100mydata <- data.frame(x=runif(n))mydata$...
That is what I read the other day. For calculation of descriptive statistics, values below the LLOQ (lower limit of quantification) were set to.... Then I wondered, wasn't there a trick in JAGS to incorporate the presence of missing data while es...
I am playing around with Eurostat data and ggplot2 a bit more. As I progress it seems the plotting gets more easy, the data pre-processing a bit more simple and the surprises on the data stay.
I want to exercise a bit more with ggplot2 and there is always data to be gotten from Eurostat which is interesting. In Netherlands the statistics agency (CBS) brought these headlines (translated with http://translate.google.nl/):Unemployment...

It is winter which makes it time for one of Netherlands beloved sports: speed skating. Speed skating is done over various distances, but for me, the most beautiful is the 10 km. The top men do this in about 13 minutes. In this post I try to u...
The Wheel of Time is a series of books started by Robert Jordan. Unfortunately he died too early. Like all fans of the series I feel very lucky that Brandon Sanderson was able to continue these books. The first book Sanderson wrote was the Gathering St...
The Eye of the World is the first book of Robert Jordan's Wheel of Time books. As the last of these books will be published soon, I was wondering if natural language processing can be used to examine books like these. For this purpose I downloaded a co...
