In STATA MP 18（Windows 10）,
I want to run the command " colelms BMI, agegroup ( 年龄分组2) sex(gender) centile( 15 25 50 ) df(2)" to get a growth fit curve，
it can calculate the mean, variance, L-value, M-value and S-value,
but it present "GAMFIT failure, $.out not found
file $.out not found
r(601) "
and the fitted growth curve could not be produced
What should I do next?
Looking forward to your reply！
