- The econometric model used to construct the Tech Pulse index is re-estimated every month. Consequently, every month the whole historical time-series of the index is revised.
- The econometric specification of the model underlying the index as well as the source data have changed substantially compared to the versions of the index released before August 2008. Therefore, the current version of the Tech Pulse index is not directly comparable to previous versions of the index published before December 2008.
