st: How to solve this problem when running separate regression using stasby or looping |

Dear All, I would like to run separate estimation equations for each individual. Using the _stasby_ command such as: statsby, by(id): nl (reward=y^{alpha=1}*{beta=0.6}*exp(-{r=0.1}*t)) Stata doesn't work since there missing value or inconvergence for some individuals. Using the loop such as: forval i = 1(1)184 { nl (reward=y^{alpha=1}*{beta=0.6}*exp(-{r=0.1}*t)) if id==`i' } The same thing happens. Can you suggest me a solution so that Stata can go on with the estimation for all "estimable" individuals and assign missing value to the case with inconergence or missing value?
