I'm an econometrician that has used Mathematica for several years. Now I've
finally decided to sit down and generalize some of my code to better
handle time series data. I'd like to get some opinions on good ways to
define a time series "data structure". Ideally this structure would
carry all of the important information about the series, e.g, the
numercial values, the corresponding dates, the frequency, information
for how to convert the series from one frequency to another (say
monthly to quarterly), the textual name of the time series (say GDP),
and some brief descriptive information.
Obviously this could be structured as a list of lists, but that strikes
me as not very elegant. I've seen examples of Mathematica code that creates
objects that remind me of traditional record data structures using up
values. Is this the preferred approach?
