Dear Statalist,
This is not a Halloween pranl. I am actually having a problem with ghost
value labels. I am not sure whence the problem arises, so I will start at
the beginning:
1) I converted a dataset from SPSS to Stata
2) I dropped all of the value labels using "label drop _all". "label list"
showed that there are no value labels.
3) I cleaned the data and labeled SOME of the values myself.
4) Some of the numeric variables that had a value label before I dropped
them, still "have" them. For example, "codebook leved27" yields
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
leved27
Highest Level of Education Completed (Self-Report)
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
type: numeric (byte)
label: V3078, but label does not exist
range: [1,99] units: 1
unique values: 12 missing .: 6/123
mean: 5.91453
std. dev: 9.32976
percentiles: 10% 25% 50% 75% 90%
2 2 3 9 10
----------------------------------------------------------------------------------
"des leved27" yields
storage display value
variable name type format label variable label
-------------------------------------------------------------------------------
leved27 byte %9.0g V3078 Highest Level of Education
Completed (Self-Report)
However, V3078 does not exist, and not all variables are effected. When I
attempt to drop the label by hand, Stata gives me an error message saying
that it does not exist. In my analysis, I segregate the variables based on
whether they have value labels (other then yesno) or not, and it would be
helpful if I could do this. This also makes me worried that there are some
deeper problems that are not merely inconvenient.
Please help!
