Statistical properties of Haar coefficients. A. The inner curve (thin curve) is the probability density function generated from generating differential coexpression coefficients grouping the data cross all possible combinations using data categorized as adult and older adult. The heavier tailed curve (thick curve) is the probability density function resulting from grouping the data by age. The dots are the calculated null distribution for the differential coexpression coefficient. The x axis is the correlation difference between the two groupings of data used. B. The false discovery rate is shown. Again, the x-axis is the difference between coexpression in older adults and coexpression in adults, when each experiment is normalized to a unit Gaussian.
