i totally agree with you! And i have the mentioned book right in front of me :).. But as this calculations are for my bachelor thesis my time frame is very limited,  i have never worked with Stata before, and i just dont have the time to learn all this (it is not even the core topic of my thesis...). i tried to, but till now i was not able to implement it, and at the University of Zürich i don't have anybody to help me with it. The excel calculations are definitely not best way but for me at my level of Skills, the only way possible... But anyways thank you for your advice, i will maybe attend the course in Italy, so i have more skills for future reasearch projects. To all of you Statalists, i really appreciate all your work to help people with Stata Problems, even with noob questions like the questions i always ask... Whitout you guys i would definitely be lost...

i will try the -reshape- and report back. Thanks
