Fig. 4From: Smoothing and extraction of traits in the growth analysis of noninvasive phenotypic dataResults of the longitudinal analyses, showing predicted PSA (a), PSA AGR (b), backtransformed PSA (c), and PSA RGR (d) for smoothing with 10 knots. The error ribbons are the predicted values ± 0.5 LSD (α  =  0.05). Separated ribbons indicate a significant difference, in contrast to overlapping ribbons for which there is not a significant differenceBack to article page
