Create six dummy variables[0, 4), [4, 5), [5, 6), [6, 7), [7, 10), and [10, 1) named wagec1, wagec2, · · · , etc.
to indicate each value of wagec.
(i) Use commands generate and replace only to complete this task.
(ii) Complete this task using a single command.
我是這樣寫~但不確定是否正確
(i)
g wagec =0
replace wagec1 = 1 if wage >= 0 & wage < 4;
replace wagec2 = 1 if wage >= 4 & wage < 5;
replace wagec3 = 1 if wage >= 5 & wage < 6;
replace wagec4 = 1 if wage >= 6 & wage < 7;
replace wagec5 = 1 if wage >= 7 & wage < 10;
replace wagec6 = 1 if wage >= 10;


(ii)
tab wage, g (wagec);
可是這樣做就不只分6組
