Le,
Can you send me an example where this occurs. At least with auto
data set example below, -set seed- appears to work:
. sysuse auto,clear
(1978 Automobile Data)
. replace mpg = 17 if mpg <17
(14 real changes made)
. set seed 12345
. cqreg2 mpg price gear, ll(17) bs reps(20)
(fitting base model)
(bootstrapping ....................)
Median regression, bootstrap(20) SEs Number of obs = 59
Raw sum of deviations 239 (about 22)
Min sum of deviations 176.8206 Pseudo R2 = 0.2602
------------------------------------------------------------------------------
mpg | Coef. Std. Err. t P>|t| [95% Conf. Interval]
-------------+----------------------------------------------------------------
price | -.001039 .0008948 -1.16 0.251 -.0028314 .0007535
gear_ratio | 6.49799 1.870249 3.47 0.001 2.751431 10.24455
_cons | 6.274038 5.979655 1.05 0.299 -5.70465 18.25273
