All,
Hiya! I've tried to run -bootstrap- after the following -corr- run:
. corr conch srconch if (srcycle>.25 & srcycle<.5)
(obs=60)
| conch srconch
-------------+------------------
conch | 1.0000
srconch | 0.6417 1.0000
. return list
scalars:
r(N) = 60
r(rho) = .6417031391377833
. bootstrap `"corr conch srconch if (srcycle>.25 & srcycle<.5)"' _N r = r
(rho), size(60) reps(1000) saving(bsout) dots replace
command: corr conch srconch if (srcycle>.25 & srcycle<.5)
statistics: _bs_1 = _N
r = r(rho)
Warning: Since corr is not an estimation command or does not set e
(sample), bootstrap has no way to determine which observations
are used in calculating the statistics and so assumes that all
observations are used. This means no observations will be
excluded from the resampling due to missing values or other
reasons.
[...]
The -bootstrap- does run, but, as the text says, it runs with _all_
observations (305 in total), and not with the 60 in the original -corr-
run.
Thus is there any way to set up -e(sample)- for -bootstrap- after -corr-
or any estimation command which for whatever reason does not set
-e(sample)-? Thanks.
