The default value for the offset $\mu$ is $0$ and for the multiplier $\sigma$ is
$1$ in case not both are specified.

For a container variable, the affine transform is applied to each element of that variable.

As an example, the non-centered parameterization of Neal's Funnel in the
[Stan User's Guide reparameterization section](https://mc-stan.org/docs/stan-users-guide/reparameterization.html),
$$
p(y,x) = \textsf{normal}(y \mid 0,3) \times \prod_{n=1}^9
\textsf{normal}(x_n \mid 0,\exp(y/2)).
$$
can be written as:

```stan
parameters {
real<multiplier=3> y;
vector<multiplier=exp(y/2)>[9] x;
}
model {
y ~ std_normal();
x ~ std_normal();
}
```
where the affine transform is applied to every element of vector `x`.

### Expressions as bounds and offset/multiplier {-}
