PLEASE NOTE:
A technical error was discovered in the weighting of all 2001 Panel files.
The Core and the Topical Module files have been replaced on the SIPP FTP site and the DataFerrett system.

2/23/05 - An additional technical error has been discovered in the longitudinal weighting (including calendar year weights) for the 2001 Panel.


3/30/05 - The longitudinal weighting file has been replaced on the SIPP FTP site and in DataFerrett.


There were cases that incorrectly received zero weights for CY2002 and the longitudinal Waves 1 - 7 and Waves 1 - 9 panel weights.  Most of these cases were persons who died between Waves 5 - 9 and therefore should have had a positive weight rather than a zero weight.

For questions pertaining to this issue contact Tracy Mattingly at 301-763-6445.
