Hola to all!

Hi everybody, my name is Tiana and I studied statistics 20 years ago. Meantime I did a lot of different jobs, and had all the time to forget what I learned ! :(
Still, I would like to try to refresh a bit my knowledge and, especially when I bump in some minor problems I can meet in real life, maybe even try to solve it with a bit of help. Hope you'll not be too tough with an old rookie! :)
