¥4-Way ANOVA: ready to rock-n-roll (for the
daring and intrepid)
HInteractive
Matlab script
HCan
run both crossed and nested (i.e., subject nested into gender)
design
HHeavy
duty computation + Matlab: expect to take 10s of minutes to hours
HSame
script can also do ANOVA, ANOVA2, and ANOVA3 analyses
HIncludes
contrast tests across all factors
HAt
present, must have a balanced design with no missing data
åequal
number of entries in each cell
åcan be
a problem when studying patients (e.g., hard to find some genotypes)
HWorking
now to implement more options, such as
åANCOVA
(ANOVA plus regression with continuous covariates; e.g., age)
íRecent
news: now working!!
åunbalanced
designs (uneven numbers of entries in cells, or levels in factors)
íRecent
news: now working for some cases!
åmissing
data (e.g., some subjects couldnÕt perform certain tasks)
¥Goal: be a user-friendly
alternative to running 3dRegAna
for most complicated analyses of group datasets
¥Goal: once program is stabilized,
re-write in C for speed and independence from the commercial product Matlab
