 * PIVOT variable = BOUND variable
 * DUMMY variable is (special case of) bound variable that can have only values 0 or 1.

The above is utter nonsense and is already covered in the article. Statisticians use the term "dummy variable" to mean something that can only be either 0 or 1. That is a completely different concept from that of dummy variable discussed in this article. And the article already says that. The "dummy variables" used by statisticians that only take the values 0 or 1 are NOT bound variables at all. Michael Hardy 22:34, 29 Apr 2005 (UTC)

The fact that you have not heard of this proves nothing unless you assert some claims to knowledge of mathematical reasoning. Combined with the fact that this usage is widespread, it proves you lack that kind of knowledge. Do you expect articles to include only things that you already know about?

Your account will be renamed
Hello,

The developer team at Wikimedia is making some changes to how accounts work, as part of our on-going efforts to provide new and better tools for our users like cross-wiki notifications. These changes will mean you have the same account name everywhere. This will let us give you new features that will help you edit and discuss better, and allow more flexible user permissions for tools. One of the side-effects of this is that user accounts will now have to be unique across all 900 Wikimedia wikis. See the announcement for more information.

Unfortunately, your account clashes with another account also called JPV. To make sure that both of you can use all Wikimedia projects in future, we have reserved the name JPV~enwiki that only you will have. If you like it, you don't have to do anything. If you do not like it, you can pick out a different name. If you think you might own all of the accounts with this name and this message is in error, please visit Special:MergeAccount to check and attach all of your accounts to prevent them from being renamed.

Your account will still work as before, and you will be credited for all your edits made so far, but you will have to use the new account name when you log in.

Sorry for the inconvenience.

Yours, Keegan Peterzell Community Liaison, Wikimedia Foundation 00:34, 20 March 2015 (UTC)
