The ISF2019 took place in Thessaloniki, Greece. This time I presented a spin-off of my research on intermittent demand in retail, entitled as “What about those sweet melons?

The idea is quite trivial and simple: use mixture distribution regressions (e.g. logistic and log-normal distributions) in order to predict the seasonally-intermittent sales in retail. The model is quite simple and easy to implement in practice. The main problem that I’ve faced so far is the absence of the proper data. I only had 24 series of weekly sales of tomatoes provided by a small company, but I need more in order to see, which of the approaches works best. For this research, I need the data like this:
