¥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
