Do not make a sum with your forecasts

Although we have tried to make Lokad as simple and intuitive as possible, statistical forecasting is a counter-intuitive science with many traps. In this post, I am going to describe one of the most frequent mistakes that I have encountered within many companies. In a nutshell, it is wrong to make a sum of forecasted values. Since the problem is quite hard to grasp, let’s start with an example. Let’s say that you have 3 shops; and that those 3 shops are selling coconuts.

Lokad gets live!

We have released the first version Lokad. This release features already a state-of-the-art AJAX-enabled web application. We have tried to provide a user experience as smooth as possible, including a lot of contextual help content. Yet, we are aware that our documentation section is quite weak at the time. If you feel that some aspects of the Lokad website and/or technology should be more documented, do not hesitate to contact us, we will be more than happy to provide answers (and possibly documentation ASAP).

Pre-release comments on COLOSSUS

My name is Joannes, I am usually blogging from my own blog, but since we have decided to setup a blog entirely dedicated to Lokad, I am going write directly on this blog. Lokad is a project that I have started one year ago. This project was initialy titled Supply Chain Optimization, Reducing inventory and Ruptures during a talk in March 2006 at the Entrepreneurship session of the Insead in Fontainbleau (south of Paris).
