In response, we have archived the predecessors (2008=100, January 2008 to January 2017) by renaming with an "_08" specifier, by marking the metadata as "discontinued," and by segregating in the catalog. The replacements (2013=100) start at January 2013. The EAI is a chained volume index, presented in seasonally adjusted (SA) and not seasonally adjusted (NSA) forms.

The series reside in the historical catalog (Chile » Cyclical Indicators » Economic activity indicator) and are:

• CIIEAC_08AM.ICHL = [DISCONTINUED] Economic Activity Index, (2008=100, SA)
• CIIEACAM.ICHL    = Economic activity index, (Ch. Vol. Index 2013=100, SA)
• CIIEAC_08UM.ICHL = [DISCONTINUED] Economic Activity Index, (2008=100, NSA)
• CIIEACUM.ICHL    = Economic activity index, (Ch. Vol. Index 2013=100, NSA)

Because catalog locations are subject to change, the upper-right search box on DataBuffet.com provides a "find in catalog" mode that accepts a mnemonic.
