Add Stimuli-Within-Block design? #3

Closed becky-gilbert closed 7 years ago

Can PANGEA handle a Stimuli-Within-Block design?

From the JEP:G Crossed Power paper, p. 2035:

the full stimulus sample is divided into a smaller number of comparable lists or blocks, and each participant is randomly assigned to receive only one of these blocks.

If not, I think this would be a useful feature.

Yes, you can fit stimuli-within-block designs (or what we call "replicated" designs in our Annual Review paper) by adding a factor called "Blocks" to the design, and then having Participants and Stimuli both nested within Blocks. The Block factor will usually be fixed, but there might be special cases where it would make sense to treat the blocks as random.

Great, thanks!
