As for Google Analytics, here is a copy-and-paste from a post I made in the forums:
1] Click on the Google Analytics link from your HubPages account
2] Click on "Filter Manager" in the lower right of the screen that comes up
3] Click on "+ Add Filter" in the right side of the next screen
4] Choose a name for your filter
5] Click on "traffic from the domains" and change it to "traffic from the IP addresses"
6] Enter your IP address (http://www.whatismyip.com/)
7] Select your HubPages profile and click on "Add ->"
8] Save changes
The easier way, in my opinion, is to download the opt-out plugin from Google: http://tools.google.com/dlpage/gaoptout . This accomplishes the same thing without having to go through the above.
