## 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 β_0, …, β_3 in eqn. (13) in Costantini et al. (2007) (see also Lupi, 2009).
