Hello, Actually I have three variables in percentage (Formal credit - semi-formal credit - Informal credit) between 0 -100%
Code:
sum Formal_credit informal_credit Semi_formal_credit

    Variable |        Obs        Mean    Std. Dev.       Min        Max
-------------+---------------------------------------------------------
Formal_credit |     81,342    15.10992    25.61789          0        100
informal_credit |     82,974    62.47527    34.42988          0        100
Semi_formal_credit |     78,439    1.368165    7.610706          0        100
Now, I am trying to create a categorical variable (e.g. Formal credit = 1, informal credit = 2, semi-formal credit = 3), but the problem, a firm can use formal and informal credit in the same time. my question How I avoid this problem?

Thanks a lot
