Depends what kind of analysis you are trying to do. If you after user and your page hits stats, logfile analysis tools such as mentioned above will do.
Other types of tracking may require some custom server site programming.
For example, I currently work on a traffic tracking code that is aimed at sites involved in affilate programs. It will allow to track which site a visitor came from (and if it cost anything), where did the visitor go (does anyone owe for the referral) and which of the ads placed with others provide the return on investment.
