Floating Point Overflow in HPFMM - how to stop it and how to stop my program terminating

kivey — Sat, 12 Jan 2019 18:50:58 GMT

I am running a marco that iterates through all variables in my dataset, and for each variable, runs a hpfmm procedure. The marco works perfectly until it reaches a variable for which there is a floating point error, in which case, the macro terminates

This is a snippet of my code and its associated error

proc hpfmm data = nf_allgpr_s4_div_ge3 seed=12345 ;
model gprPWY_5971_s4 = / kmin=1 kmax=3 dist=STUDENT ;
ods output ConvergenceStatus=myConvergenceStatus ;
run;

ERROR: Floating Point Overflow.

ERROR: Termination due to Floating Point Exception
NOTE: The SAS System stopped processing this step because of errors.

I have tried the above program with proc fmm, and get the same issue

My questions are

How can I get SAS to stop producing the floating point error?
If that is not possible, how can I get my macro to continue to iterate to the next variable in my dataset, rather than terminating the program, when a floating point error arises?

Thank you so much for your input

You should report the floating-point overflow to SAS technical support. Include the data for the gprPWY_5971_s4 variable and the information about your SAS version.

1. You can try rescaling the gprPWY_5971_s4 variable. Use PROC MEANS to see if that is a likely problem. Sometimes data that has extreme ranges (eg, a range of values such as [0, 1e9]) can lead to overflows. If the variable has a wide range, try using PROC STDIZE to rescale.

2. To skip the variable use the DROP statement in your macro:

proc hpfmm data = nf_allgpr_s4_div_ge3(DROP=gprPWY_5971_s4 ) ...
