Dear Sir,
When I study the (DHS Methodological Reports No.12) about the Quality and Consistency of
DHS Fertility Estimates, 1990 to 2012. I wish to recalculated displacement index in the Appendix Table A1. Description of the 182 DHS surveys (1990-2012) used in this report for EDHS 2008 by this steps: by (tfr2) Found the number of birth per year for 7 years before the survey 2008

2- Displacement of births from year 0 (cutoff year) at (TFR_4) and after that I use the equation from 1 to 4 in p 25-26 from the report

Db = I2034.074 - 2800.027I = I1090.445 - 1856.398I =765.9536

DISPL= 0.70
TFR= 3.127114
Displacement index= 0.70/3.127114= 0.22 # 0.15 as in the report (I Know I did mistake? but where please help me!

Thank you in advance
