1. Introduction

I'm prepare to make an estimate of lotto numbers. As a result of searching, some sites are serve this service. 

This works only for fun to me, but to make an estimate of lotto numbers is surely hard working. However, 

obviously, when I try to use some mathematical methods, I can be learn a lot from this work, and maybe it 

helps mywork ,too. Therefore, I anticipate great plasure from its works. :)
