When I do simulation, the result will show all prior parameter and the variable i defined in generated quantities. If I just want show the result for aie, ade, and aie2 only. how to avoid other defined variables showed from the final result.

```
generated quantities{
real ie1[N];
real ie2[N];
real de[N];
real aie1;
real aie2;
real ade;
for (i in 1:N){
ie1[i]=alpha1*beta1*(exp(alpha1*X[i])/(1+exp(alpha1*X[i]))^2);
ie2[i]=alpha2*beta2;
de[i]=c;
}
aie1=mean(ie1);
aie2=mean(ie2);
ade=mean(de);
}
```
