st: Backfill Missing Values |

Hello! I have a panel dataset that looks something like this: year gdpReal gdpNom gdpdefl PPI dPPI 1900 126 . . 25 1901 132 . . 27 .08 1902 138 . . 29 .074 1903 142 . . 31 .069 1904 147 41.16 28 32 .032 1905 150 48 32 34 .063 1906 151 49.83 33 35 .029 The variable I need is gdpNom. Normally, one would obtain this as: gdpNom = gdpReal * (gdpdefl/100);

So, I want to estimate gdpdefl using dPPI, something like this: gen gdpdeflFILL = F.gdpdefl/(1+F.dPPI) if gdpdefl==. gen gdpdeflEST = gdpdefl replace gdpdeflEST = gdpdeflFILL if gdpdeflEST==. This would allow me to estimate gdpNom: gen gdpNomEST = gdpnom replace gdpNomEST = gdpReal * (gdpdeflEST/100) if gdpNomEst==.

Any help would be much appreciated. Thanks, Paul Rivera * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
