For each probe set, the within-replicate variance averaged across nominal concentrations is used as a measure of precision, and the nonlinearity of the signal detect curve is used as a measure of accuracy. The mean and SD across probe sets is reported for each preprocessing algorithm.
Note: MM, mismatch; BG, background correction.
