I’ve recently delivered a three-day intensive short-course on Scala for statistical computing and data science. The course seemed to go well, and the experience has convinced me that Scala should be used a lot more by statisticians and data scientists for a range of problems in statistical computing. In particular, the simplicity of writing fast … Continue reading Statistical computing with Scala free on-line course
Introduction Today, I will begin a series of posts on numerical integration, which has a wide range of applications in many fields, including statistics. I will introduce trapezoidal integration by discussing its conceptual foundations, write my own R function to implement trapezoidal integration, and use it to check that the Beta(2, 5) probability density function […]
I let Andrew know about the comments about the defective Kindle version of BDA2 and he wrote to his editor at Chapman and Hall, Rob Calver, who wrote back with this info: I can guarantee that the Kindle version of the third edition will be a substantial improvement. We publish all of our mathematics and […]The post Improvements to Kindle Version of BDA3 appeared first on Statistical Modeling, Causal Inference,…
Update on July 15, 2013: Thanks to Harlan Nelson for noting on AnalyticBridge that the ozone concentrations for both New York and Ozonopolis are non-negative quantities, so their kernel density plot should have non-negative support sets. This has been corrected in this post by - defining new variables called max.ozone and max.ozone2 - using the […]
For the sake of brevity, this post has been created from the first half of a previous long post on kernel density estimation. This first half focuses on the conceptual foundations of kernel density estimation. The second half will focus on constructing kernel density plots and rug plots in R. Introduction Recently, I began a […]
A question that often comes across various help lists is how to combine or split an output from an R graphics device. Maybe you have looped/combined multiple visuals into a single pdf to avoid cluttering your working directory and now … Continue reading →
