MAPA package for R on GitHub

Here is the link: https://github.com/trnnick/mapa It has been a long time I wanted to rework the MAPA package for R, but I could not find the time. Finally I got around starting it. There are three objectives in this: Clean up code and introduce S3methods. MAPA was the first package that I wrote! Incorporate the… Read More »

ISIR 2016 research presentations

Last August I attended the International Symposium on Inventories, organised by the International Society for Inventory Research (ISIR 2016). This is the second time I had attended this conference and it has been again a very good experience. Interesting talks on a variety of relevant topics to forecasting research. I organised a special track on… Read More »

International Symposium on Forecasting Presentations

Last week I attended the International Symposium on Forecasting 2016. It was very interesting and enjoyable. Apart from the workshop on forecasting with R, I gave the following presentations: Forecasting with Temporal Hierarchies This presentation was given to the practitioner track of the conference and its aim was to introduce the basic idea of temporal… Read More »

Material for `Forecasting with R: A practical workshop”

Together with Fotios Petropoulos we gave a workshop on producing forecasts with R, at the International Symposium on Forecasting, 2016. You can find the material of the workshop here. The workshop notes assume knowledge of what the various forecasting methods do, which are only briefly explained in the workshop’s slides, and mostly focuses in showing… Read More »

Forecasting with Temporal Hierarchies

This is a talk that I am giving today at the University of Sydney Business School. This research builds upon MAPA and cross-sectional hierarchical forecasting, in particular optimal combinations. Temporal hierarchies reconcile across time, resulting in accurate short and long-term forecasts that can lead to aligned plans and decisions. Temporal hierarchies can be used with… Read More »

ISF 2015 and invited session on “Forecasting with Combinations and Hierarchies”

The International Symposium on Forecasting (ISF 2015) was held this week in Riverside, CA. It was a very interesting conference, with stimulating talks and a wide variety of forecasting related topics, both for academics and practitioners. It is a highly recommended conference to attend. I organised the invited session on the topic of “Forecasting with… Read More »

Experimenting with Shiny for R

Shiny is a web application framework for R. The idea is simple: deploy R code in webpages. This might prove useful when user interaction is required, for instance to design and deploy forecasting experiments that need human participants. I gave it a try to see how easy is it to build a demo. Assuming your… Read More »

MAPA and intermittent demand forecasting

Recently I posted about a paper I co-authored with Fotios Petropoulos, now in JORS: Forecast Combinations for Intermittent Demand. There we found that for intermittent demand data using multiple levels of temporal aggregation, forecasting them with the appropriate models and finally combining the forecasts performed best. This approach has many analogies with the MAPA algorithm… Read More »
