All,

I have a variable that records the year an event occurred, but about 10% of
the observations are missing.† When I run -ice-, some of the imputed values
are future years...† However, the mean imputed values for each missing
observation are actually ok (<2007).† Are the coefficients, standard errors,
etc still ok?† If not, how do you limit the imputed values to < 2007?† I
donít see how the -ice- syntax allows for this.

Also, when I used -micombine- along with -reg- (micombine reg [varlist]),
the ANOVA table, R-squared, RMSE, etc did not show up. Is there a
theoretical reason why these donít appear?

Thanks,
Mark
