PronoEuroX is statistics software for Windows: it reads the history of past EuroMillions draws and draws figures from it. It is stats software in the everyday sense — frequencies, gaps, charts — and it is statistical analysis software for Windows in the strict sense: a desktop application installed on your own computer, working on data stored locally.
Seen as a statistical analysis tool, it prepares past data (the date, the numbers and the stars of each draw), computes indicators over the period you choose, then presents the result as tables and curves. It is data analysis software as well, applied to a single data set: the draws that have already taken place.
Statistical software describes the past, and nothing else. The combination reducer organises combinations that are already possible, according to filters you set yourself: it changes neither the probability of a draw nor the result to come. No statistical calculation can improve your chances of winning.
Everything is adjustable: the period, the years, the filters. The figures displayed are always recomputed from the history recorded on your machine.
