It is about sas programming. Thank you in advance.
I build an ordinal logistic regression model on my data.
Level Meaning 3 Alert 2 Unusual Event 1 Non Emergency
As you can see, it is my ordinal response variable. 3 means large loss and Alert situation, etc. I build a very simple model, the graph below shows the result:
proc logistic data = sasuser.Pacific_West_ outmodel=sasuser.Pacifici_West_model;; model Numerical_Emergency(event = '1') = AGE; run;
Everything looks fine. Now I would like to apply the BOOTSTRAP method to validate this model. What thing I would like to see is the test c value as ROC value. As you may see in the graph above, the c (ROC) value is 0.640. The basic idea of bootstrap is to generate new data set by random picking process from the data we used to train the model as we all know. I prefer to generate 1000 copies of data with same size of original data for building the model in graph above.
In the SAS Score statement, I just found outroc method which does not support the ordinal regression. Is there a simple procedure to help me to output the statistics about fitting of trained model on the validation dataset build by myself?
Thank you so much for your time. Have a nice day!
