unitroot_nsdiffs()
provides the repeated testing procedure for identifying the number of differences required to achieve stationarity.
It doesn't enforce the seasonal strength test to be used, however the default is based on the seasonal strength.
I think some clarification regarding the default test for unitroot_nsdiffs()
is required, and some guidance on using alternative tests.
It does not use unit roots for the number of seasonal differences.
