Dear Statalist,

What am I missing? I am trying to apply the El-Badry correction to census data.

I began by creating a counting variable within each age category (15-49).
Then I did the following:

regress pnsborn pzeroborn  /*restricting the analysis to the first observation*/
predict yhat /*predicted values from the regression model*/

*Produced a scatter plot with regression line added
graph twoway lfit pnsborn pzeroborn || scatter pnsborn pzeroborn

*Compute residuals, create new variable residuals:
predict residuals, resid

*Produce a residual plot by age groups with horizontal line at 0
*Should be no pattern
twoway (connected residuals age3, sort), ytitle(residuals) yline(0)
xlabel(#12, labels valuelabel)

The graph is actually showing a pattern- when there should be none.
What have I either done wrong or failed to add?
