Mean recovery of (left panel) and (right panel) for all combinations of the levels of 'Noise Total' and 'Noise Ratio'. The RV-Z is indicated on the y-axis. The three levels of 'Noise Total' are indicated on the x-axis. The different lines indicate the levels of the factor Noise Ratio (red, dashed, square = NoiseX1 < NoiseX2; solid blue, diamond = Equal; black, dashed, triangle = NoiseX1 > NoiseX2). The RV-Z values were averaged over the other factors, e.g., the factor Method.
