Dear Friends:
When I use graph matrix to draw matrix graphs, I got the error message:
. graph matrix `covariates'
value label M06_Q01 not found
no variables defined
no variables defined
no variables defined
When I draw histgram, I also got an error message
. hist c06_gangs
(bin=35, start=0, width=.02857143)
value label M06_Q01 not found
no variables defined
no variables defined
no variables defined
r(111); t=0.33 20:46:29
I found a way out just now: generate a new variable and let it equal to c06_gangs, then operate on the new variable.
However, I would like to figure out the reason for the error.
This is desribe of variables.
