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.
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).
