Hi,

I need your help. When we run a simple regression, we may access the coefficient by typing
Code:
_b[x1]
,
Code:
_b[_cons]
, etc

Code:
. reg y x1 

. di _b[x1]
1.6517423

. di _b[_cons]
3.1274369
How can we access the coefficients in two regions of a threshold regression? If I type the same command as above, I got the coefficient estimate for region 1, but I do not know how to get estimate of region 2. Thank you very much.

Code:
. threshold y, threshvar(z) regionvars(x1)


Full sample:    1 - 2282                         AIC              =  6566.4751
Number of thresholds =  1                        BIC              =  6589.4063
Threshold variable: z                       HQIC             =  6574.8388
