Hi! I would like to specify a model, where a_3 > a_2, where a_2 and a_3 are parameters. I have done this as follows:

```
parameters {
real<lower=0> a2;
real<lower=a2> a3;
}
model {
a2 ~ normal(1.5,0.75);
a3 ~ normal(1.5,0.75);
}
```

Is this okay? Or should I be using the transformed parameters block?
