unitroot_options(ndiffs_alpha = 0.05, nsdiffs_alpha = 0.05,
ndiffs_pvalue = ~feasts::unitroot_kpss(.)["kpss_pvalue"],
nsdiffs_pvalue = ~feasts::feat_stl(., .period)[2] < 0.64)

## Arguments

ndiffs_alpha, nsdiffs_alpha The level for the test specified in the pval functions As long as pval < alpha, differences will be added. A function (or lambda expression) which returns the probability of the . As long as pval < alpha, differences will be added. For the function for the seasonal p-value, the seasonal period will be provided as the .period argument to this function. A vector of data to test is available as . or .x.
