The statistics show the occurrences of combinations of six and more numbers. The statistics are available only for lotteries that draw 7 and more numbers.
Note: The statistics are not available if there are too many possible combinations. For example in a x/80 Keno lottery there are over 300 millions of possible combinations of six numbers. It is possible to override this limit by starting Expert Lotto with -J-Dstats.combo.nolimit=true command line switch. However in that case the application may refuse to calculate the statistics if there is not enough free RAM memory.
