Recently, I found that there is a translation error of the Odds Ratio Estimates results from PROC LOGISTIC in chinese version. I use the data set CARS form SASHELP library to do a demo, just ignore the model effect. Here is the SAS code:
where DriveTrain in ('Front', 'Rear');
proc logistic data=test plots(only)=all;
class type(param=ref) origin(param=ref);
model DriveTrain (event = 'Front')=msrp enginesize horsepower mpg_highway origin;
The Odds Ratio Estimates from English version:
For the OR estimate of CLASS variable Origin, 'USA' is the reference level.
Asia vs USA
Europe vs USA
This is correct. But for Chinese version, here is the result:
At first I couldn't understand the result, why it's "USA-Asia"? "USA" is the reference level, it makes me confused. Somehow I find it is correct in English version.
So, I guess this is a translation error. Or is there some other reason?
