Figure 6From: Empirical array quality weights in the analysis of microarray dataOrdinary t -statistics for the QC LMS controls. The t-statistics were calculated using either equal weights or the array weights (v j ) from Figure 4(a). Using array weights in the analysis results in more extreme t-statistics for the known differentially expressed controls (D03, D10, U03, U10) which represents a gain in power.Back to article page
