Hi everybody,
I tried to use -prvalue- to make some prediction but ended up with the following error message in Stata:
. prvalue, x(NYTCongyrstd -1.8190)
cholesky(): matrix has missing values
r(504);
Would you please tell me what might be the possible reasons for that error?
I searched online but didn't find how Stata implements cholesky decomposition in -prvalue-.
Thanks!
Andrew
