December 2011

Hello! I'm a bot created by another Wikipedia editor. I wanted to let you know that I removed a link that you recently added to the page Covariance here. I did this because http://khanglab.files.wordpress.com/2011/06/covariance.jpg?w=640&h=632 is probably inappropriate for an encyclopedia. Instead of linking to an external image, you can find images already available or use the upload wizard if you'd like to add new free content.

We appreciate your help in making Wikipedia better for everyone. If I made a mistake, feel free to undo my edit. If you have any questions, you can ask at the Help desk.

Thank you! --XLinkBot (talk) 02:40, 3 December 2011 (UTC)

In response to your feedback

I just wanted to say thank you for your continued edits to covariance. If you ever need anything, the Help Desk is a good place to ask.
