I mark several channels and type "Layout change October 26th"
The program tells me from day to day, how statistical significant are the changes in views, eCPM, EPC and so.
Any idea for such a software?

You can use built-in Excel functions (Student t-test, which assumes normality) to compare means of two samples, or G "online calculator mann whitney" for test which does not relies on normality of your data. [en.wikipedia.org...] contains a link to one of them.
Of course, you can search for a program with good-looking UI, 3D buttons, MP3 player and so on... :) But it will just compare two samples.
