CrossValidated Journal Club
Journal Clubs are a great way to learn new research ideas and to keep up with the literature. The idea is that a group of people get together every week or so to discuss a paper of joint interest. This can happen within your own research group or department, or virtually online. There is now a virtual journal club operating in conjunction with Cr...

Research position in forecasting renewable energy
I don’t normally post job ads except when they are within my own research group. But this one is close to my research interests, and I’d like to help the institution find someone good for the role, so I’m making an exception. It is a position for a post-doctoral researcher at the Centre for Energy & Processes, MINES Paris Tech, France. The ...

RStudio: just what I’ve been looking for
For many years I used RWinEdt as my text editor for R code, but when WinEdt 6.0 came out, RWinEdt stopped working. So I’ve been looking for something to replace it. I’ve tried Tinn-R, NppToR, Eclipse with StatET and a couple of other editors, but nothing was quite right. Then yesterday, out of the blue, RStudio was announced and it looks fant...

Statistical tests for variable selection
I received an email today with the following comment: I’m using ARIMA with Intervention detection and was planning to use your package to identify my initial ARIMA model for later iteration, however I found that sometimes the auto.arima function returns a model where AR/MA coefficients are not significant. So my question is: Is there a way to f...

Comparing HoltWinters() and ets()
I received this email today: I have a question about the ets() function in R, which I am trying to use for Holt-Winters exponential smoothing. My problem is that I am getting very different estimates of the alpha, beta and gamma parameters using ets() compared to HoltWinters(), and I can’t figure out why. This is a common question, so I thought...

Major changes to the forecast package
The forecast package for R has undergone a major upgrade, and I’ve given it version number 3 as a result. Some of these changes were suggestions from the forecasting workshop I ran in Switzerland a couple of months ago, and some have been on the drawing board for a long time. Here are the main changes in version 3, plus a few earlier additions ...

Time series cross-validation: an R example
I was recently asked how to implement time series cross-validation in R. Time series people would normally call this “forecast evaluation with a rolling origin” or something similar, but it is the natural and obvious analogue to leave-one-out cross-validation for cross-sectional data, so I prefer to call it “time series cross-validation”....
