| Subject | st: Imputing, interpolating, or otherwise finding missing data? |

Hi! I have a dependent variable that nicely follows the equation y=-91.78*ln(x) + 433.73. y is a growth rate, x is time(1,2,3, etc). I have several missing growth rate values, and I'd like to either impute or interpolate. I could predict values of y based solely on the equation, but I'd like to use one of the Stata functions to introduce noise around the predicted variables. I can't seem to find a way to incorporate the values of this equation into either ipolate or ice. I use Stata 10.1 (no mi function). Any ideas out there? Thanks!! * * 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/
