{title:Description}

{phang2}
{bf:haldrup} - Haldrup (1994b) Table 1 critical values for the
residual-based ADF I(2) cointegration test (intercept included).
Returns 1%, 2.5%, 5%, 10% critical values for the supplied (m1, m2,
T).{p_end}

{phang2}
{bf:johansen} - chi-squared(df) thresholds at 1%, 5%, 10% used by the
Paruolo Q(r, s_1) test.{p_end}

{phang2}
{bf:dp} - Pantula (1986) F-test critical values used by the
Dickey-Pantula sequential strategy in {helpb mixi12_unit}.{p_end}
