Details

The format of the data is essentially that of the RDS file format as specified in page 7 in the RDS Analysis tool manual: http://www.respondentdrivensampling.org/reports/RDSAT_7.1-Manual_2012-11-25.pdf.

The RDS format has been augmented with the time of interview (interviewDt variable) required for the methodology in [1].

The interviewDt variable encodes the time of interview. For the purpose of calling Estimate.b.k the scale and origin are imaterial. We thus use an arbitrary efficient encoding which might not adhere to the original scale.

For full details see the Source section.
