Generate three dummy variables

[Swadip Bhattacharjee]

Hi Scholars,

I need to create 3 dummies from one specific variable, for example,

gen d.var=1 if variable>0
replace d.var=-1 if variable<0
replace d.var=0 if variable=0

Here, I need to create d.var=0 if variable=0; however, the last Stata code is not working. Would you please help me to generate three dummies like this?

I see only a single variable being generated.

generate byte d_var = sign(variable) if !mi(variable)
help sign()

You can then use tabulate . . . , generate() to create three indicator variables from d_var.
