st: data manipulation question
I have a variable naming question, after encoding.
I used these commands,
encode iso_str, generate(iso)
tab iso, gen(iso_)
"iso_str" was a variable with these levels:
. levels iso_str
`"IDI"' `"IDV"' `"IGI"' `"IGV"' `"INI"' `"INV"' `"ISI"' `"ISV"'
`"MDV"' `"MNI"'
> `"MNV"' `"MSI"' `"MSV"' `"VDI"' `"VDV"' `"VGI"' `"VGV"' `"VNI"'
`"VNV"' `"VSI"
> ' `"VSV"'
and so iso has these levels
. levels iso
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21
after tab iso, gen(iso_)
I wind up with 1,0 indicator variables for each level of iso, with
useful variable labels. But really I'd like to have indicator
variables named for each level, like "IDI" instead of "iso_1". How do
I do that?
storage display value
variable name type format label variable label
