Hi Duckhye Yang,
For the first part, u can use the following code:
Gen sex1=0 if sex=="F"
Replace sex1=1 if sex=="M"
For the second part, what I would do is to create the dummy variables:
Tab age, gen(age_)
This would create the variables age_1 age_2  age_3, each one representing
your different groups.
Then in your probit model, you just skip the category you want to use as
base.

Dear Statalist,
I have sex variable where F and M exist.
I'd like to change the variable name to female where 1=F and M=0. Female
should be numeric variable. 
 
I have age variable, which is categorical variable (1=infant,... 5=18+).
When I ran a logit model, I found that 1 is reference category. How can I
make 5 reference category?
 
Sorry that I ask too-easy questions. I am a novice user of stata. I really
want a try!
 
Thanks,
Duckhye Yang
