A new paper on anomaly detection: robjhyndman.com/publications... The methods are implemented in the weird #rstats package.

Rolling scaled forecast accuracy – Rob J Hyndman When we compute a MASE or RMSSE using a rolling origin, should the scaling factor be recalculated every time?

Some thoughts on forecast accuracy using rolling scaled measures robjhyndman.com/hyndsight/ro... #rstats

forecast package v9 – Rob J Hyndman

After 9 years, I thought it was time for another major release of the forecast package for #rstats! New modelling functions, missing values now handled in ETS models, and a more consistent interface. robjhyndman.com/hyndsight/fo...

I also went looking for this recently. It's on the front page of CRAN (cloud.r-project.org), scroll down to the red text near the bottom of the page.

My favourite learning from #ASC2025 was from @robjhyndman.com

The goal of forecasting isn't always to be correct, it can be to influence policy

If you're successful, the forecast is probably wrong now and that's good

NNs will never win if used as a local model (fitted to a single series). But they can be better as a global model (fitted to many series). However, LightGBM has won recent forecasting competitions, not NNs.

In the latest episode🎧of The Random Sample, host Cynthia Huang catches up with Dr Hadley Wickham @hadley.nz! Hadley is Chief Scientist at Posit (formerly RStudio), where he leads the Tidyverse team. This team is behind some of the most widely used open-source packages in the R programming language.
