Hi
I am interesting to use my own reference model. so, I tried to use the reference option with Oaxaca decomposition.before I start I did quick check as follow: I used group indicator in the stored model. thus, I expect to find similar result with pooled option. unfortunately, the result was not equal. and I got a notice :

(_IQualifica_2 _IQualifica_3 _IQualifica_4 _IQualifica_5 _IQualifica_6 _IQualifica_7 _IQualifica_8 _IQualifi
> ca_9 _IQualifica_10 _IQualifica_11 _IQualifica_12 _IQualifica_13 _IQualifica_14 _IQualifica_15 _IQualifica
> _16 _Icolour1_1 _Icolour1_2 _Icolour1_4 _Icolour1_5 _Icolour1_6 _Icolour1_7 _ISIZE_1 _ISIZE_2 _ISIZE_3 _IS
> IZE_4 _Iregions21_1 _Iregions21_3 _Iregions21_4 _Iregions21_5 _Iregions21_6 _Iregions21_7 _IActivitie_1 _I
> Activitie_2 _IActivitie_4 _IActivitie_5 _IActivitie_6 _IActivitie_7 _IActivitie_8 _IActivitie_9 _IActiviti
> e_10 _IActivitie_11 _Ioccupatio_1 _Ioccupatio_2 _Ioccupatio_3 _Ioccupatio_4 _Ioccupatio_5 _Ioccupatio_6 _I
> occupatio_7 _Ioccupatio_8 missing in reference model; assumed zero)

kindly, can somebody guide me how can I prefer this option correctly
