Fixing Invalid EDF Dates

Over the past two days we've updated EDFs across the site due to an issue identified with our original approach in scrubbing the EDF start date of recording. What Happened In order to have EDFs deidentified before being posted on the NSRR, the EDFs had their header start date set to "00.00.00". This seemed reasonable as it clearly indicated that the date had been removed, while adhering to the "dd.mm.yy" format for writing a date in the signal header. Keep reading

CHAT 0.5.0 Dataset Released

Today we released a new version of the CHAT dataset. There were a handful of tweaks made to the primary CHAT dataset, including the removal of an identifiable variable (recruitment site) and clarification of the household income-related variables.
