Subject:      PROC NLP Warning and Error
Content-Type: text/plain; charset="us-ascii"

I'm running PROC NLP to estimate a log likelihood function and I've come
across a warning and error message in the log that I was hoping someone
could provide more detail about.

 

The warning message is:

 

WARNING: Your program statements cannot be executed completely. 

 

Which is followed by:

 

NOTE: FCONV convergence criterion satisfied.

NOTE: At least one element of the (projected) gradient is greater than
1e-3.

WARNING: In a total of 8 calls an error occurred during execution of the
program statements. 

         NLP attempted to recover by using a shorter step size.

 

 

 

And the error message is:

 

ERROR: Not enough memory to generate code.

NOTE: The SAS System stopped processing this step because of
insufficient memory.

WARNING: The data set WORK.EST may be incomplete.  When this step was
stopped there were 0 

         observations and 0 variables.

 

Which occurred when it was writing out the OUTEST data set, but when I
checked WORK.EST the estimates were there. Is there an explanation for
this? 

 

Thanks,

Andy
