Associative vs. Positional Indexing

When accessing array elements from Analyica expressions, we must identify which position along an index that we wish to access. In Analytica, this can usually be done either associatively or positionally.

Suppose Index Year has the following elements:

Year → {| 

border="1" || 2007 || 2008 || 2009 || 2010 || 2011 || 2012 |}
