PROC FCMP Warning

[Stepik]

Dear team,

Can someone explain the next Warning and how it can be resolved inside the PROC FCMP function?

N = CDF('NORMALTGAUSS', 1);

R2 = (y*N);

if n='false' and x ne 1 then RA = R2*m;

else...

WARNING: The variable 'n' should not be the result of the '=' operation because it is a read-only argument to 'RA'. Any changes
to this argument will not be returned from 'RA'. Use the OUTARGS statement to allow return values.

Hello @Stepik,

Variable names in SAS are case-insensitive, so n and N are the same. Most likely you used n as an argument (more precisely:  a character argument) to function RA in the FUNCTION statement, but then you use N like a numeric variable to store a probability. Just use a different name for this numeric variable.

I'm curious where in the documentation you found a 'NORMALTGAUSS' distribution. Is it different from the 'NORMAL' distribution?

Hint: It's best practice in the SAS Support Communities to show the entire log of a DATA or PROC step if you get an unexpected note, warning or error. (Use the window opened with the </> button to preserve formatting of the pasted log text.) In this case we would have seen the FUNCTION statement with the argument n.

Hi @FreelanceReinh , it is working. Thanks.

It is the same as the normal CDF normal
