¥3dRegAna: ANOVA with
unequal samples
H3dANOVA2 and 3dANOVA3 do not allow for unequal samples in each combination of
factor levels
åCan use 3dRegAna to look for main effects and
interactions
åThe analysis method involves
the use of indicator variables so it is practical for small for
small number (~3) of factor levels
HDetails are in the 3dRegAna
manual
åmethod is significantly more
complicated than running ANOVA; you must understand the math
åavoid this, if you can,
especially if you have more than 4 factor levels or more than 2
factors
åInteractions hard to
interpret, and contrast tests unavailable
HWill be easier to run
analysis in Matlab script for 3dANOVA4, when ready!
