Hello,

 

Here is my code. The response variable is L_Status and it is binary (0,1) but I keep getting an error in regards to event=1 and ref=1.

Error code is below.

 

 

 proc logistic data = traina;
class Gender Married N_Dependents Self_Employed Property Education (ref='1')/ param = ref;
model L_Status (event='1') = Credit_History N_Dependents Self_Employed L_Amount_Term Gender Married Property L_Amount Education Applicant Co_Applicant;
run;

 

ERROR: Class event parameter "1" not known.
NOTE: Procedure logistic step took :

351 quit; run;

356 proc logistic data = traina;
357 class Gender Married N_Dependents Self_Employed Property Education (ref='1')/ param =
357 ! ref;
358 model L_Status (event='1') = Credit_History N_Dependents Self_Employed L_Amount_Term
358 ! Gender Married Property L_Amount Education Applicant Co_Applicant;
359 run;
ERROR: Class event parameter "1" not known.

The error, I suspect is for your 'Education' variable in the class statement.

 

Thanks,

Rajesh.

Hi Rajesh,

 

That is not it. I still get the same error.

 

Not sure why that would have been a problem?

You can also try this code instead if your outcome is coded as a numeric variable with 0 and 1.

 

 proc logistic data = traina desc;
class Gender Married N_Dependents Self_Employed Property Education (ref='1')/ param = ref;
model L_Status = Credit_History N_Dependents Self_Employed L_Amount_Term Gender Married Property L_Amount Education Applicant Co_Applicant;
run;

Thanks,

Rajesh.

Sorry. That does not work. That is tough pretty much the same as my code.

So you mean, you got the same error when using the code I posted?

 

I removed event='1' from your code and added 'desc' option in the first statement.

 

Thanks,

Rajesh.

Hi Rajesh,

 

When I remove event='1' it says Class reference parameter 1 not known.

 

Basically, it is now complaining about the  (ref='1')/ param =
ref; part

What are the actual values of your EDUCATION variable?

Figured it out. For some reason my response variable was still character. I just converted it to numeric.

Class variables can be character you just need to address the reference level correctly, such as the full text of a value or use keywords FIRST or LAST, though sort order of character may not yield the desired order until familiar with character sorting.

Hello ballardw,

 

Can you give me an example of what you mean? (how it can be handled another way).

 

also, is it ok how I addressed it? (converting it?)
