Exchange blocks for unpaired t-test
Hi Andrew,
I have seen the NBS documentation regarding the exchange blocks in the context of repeated measure design. In the Table 12 of Anderson Winkler's PALM paper in Neuroimage (2014), exchange blocks were also defined in the context of unpaired t-test (no repeated measure). Group variances were not assumed to be the same. If I have 2 and 3 subjects in group1 and 2, the exchange block will be [1;1;2;2;2]. However, NBS shows error message if I supply this exchange block.
Is it possible to supply exchange block in NBS for un-paired t-test? What will be the structure of the exchange block for the above mentioned example?
Thanking you,
Mc
