Subject: st: Change of reference group in linear multiple regression analysis
Hi, I'm currently running a linear multiple regression analysis where the principle explanatory variable is:
Years since |
immigration | Freq. Percent Cum.
------------+-----------------------------------
<3 yrs | 106,794 3.57 3.57
3-5 yrs | 91,311 3.05 6.62
6-10 yrs | 96,657 3.23 9.85
11-19 yrs | 82,344 2.75 12.61
20-29 yrs | 50,954 1.70 14.31
>=30 yrs | 2,563,396 85.69 100.00
------------+-----------------------------------
Total | 2,991,456 100.00
- Currently the default group is the first category, <3yrs. I would however like to change this in the regression to the last group >=30 years. How do I do this without having to recode the above variable?
Thanks,
/Amal.
