In conjunction with a space-time modeling effort we are looking for data
of the following form:
For a large number of credit cards we would, ideally, like the following
information individual cards:
For each uses of a specific credit card: all of the locations (zip code
or better) at every time of use (day or better). Data over a year would
be quite useful.
That is for a large sample, trace the space-time paths of individual
cards (if one person uses more than one card, combine these data).
Individuals need not be identified.
Can anyone suggest such a data source?
Thanks to all
