Figure 2From: Quadratic regression analysis for gene discovery and pattern recognition for non-cyclic short time-course microarray experimentsHistogram of the Shapiro-Wilk p-values for normality test. The Shapiro-Wilk statistic was applied to the olfactory receptor neuron data for normality test. The horizontal axis is the Shapiro-Wilk p-values, and the vertical axis is the corresponding percentages. This histogram indicates that most of the 3834 present genes do not have a significant departure from the normality.Back to article page
