Hypothesis Testing, Power and Sample Size Determination for Between Group Comparisons in fMRI Experiments
Abstract: Modern methods for imaging the human brain, such as functional magnetic
resonance imaging (fMRI)present a range of challenging statistical problems. In
this talk, we will look at a number of possible models for the analysis of fMRI
data from multiple subjects, and develop tests that lead to calculations of
power and sample size for between group comparisons. Sample size calculations
are particularly critical for neuroscientists who use these new techniques,
since each subject is expensive to image.
There will be a Tea around 3:15pm.
