Naming Conventions

When adding a proof to "The Book of Statistical Proofs", please try to adhere to the following rules:

1. The title of a proof typically combines the name of the theorem with the topic it belongs to.

   Example: "Linear transformation theorem [theorem] for the multivariate normal distribution [topic]".

2. The shortcut of a proof typically connects abbreviations of the topic and of the theorem.

   Example: mvn [for "multivariate normal distribution"] + ltt [for "linear transformation theorem] = mvn-ltt.
