We have been notified of a problem with the AMP module in the Advance Release of the 2008 ANES Time Series study (Variables V085310 to V085358a). The problem is due to an error in one of the computer programs that was written to implement the AMP on the ANES. We are currently researching the matter. We expect to have a detailed explanation of the problem and its implications for the usage of AMP variables posted within the next two weeks. If you are interested in analyzing the AMP data, we advise that you wait until we post a full explanation of the error. This information will be posted on this website as soon as possible.
