If I write the following in stan file, then what priors are used by `rstan::stan()`

? In model block I do not write any distributions for parameters `m,v`

.

I think for parameter `m`

the constant function is used.

I think for parameter `v`

the constant function which is one on the interval [o,\infty] and 0 on otherwise.

Or is it used the inverse gamma? I am not sure what priors are used?

```
parameters{
real m;
real <lower=0>v;
}
```
