## Tables of coefficients to compute p-values

### Description

These tables contain the response surface coefficients needed to compute the p-value of Hansen's
CADF test (see Costantini et al., 2007; Lupi, 2009). `coeffs_ct`

, `coeffs_c`

,
`coeffs_nc`

are the relevant tables for the constant plus trend, constant, and
no constant case, respectively.

### Usage

```
data("coeffs_ct")
data("coeffs_c")
data("coeffs_nc")
```

### Format

The tables are saved as binary data `.rda`

objects. They are `(1005 \times 5)`

matrices,
where the first column represents probabilities and the following four columns are
`\beta_0, \ldots, \beta_3`

in eqn. (13) in Costantini et al. (2007) (see also Lupi, 2009).
