Table 4:

Details of the fitted curves on the observed postnatal weights, grouped by gender. The window length in days and the samples of each fitted curve are provided. The final (9th) column shows the L1-norm between a vector composed of the parameters of each model, (γ), and the target vector given by average of the metrics provided in Table 1, (τ), which corresponds to a nadir of 3.5 days; a weight loss at the nadir of 7.8%; a weight recovery duration of 11.2 days; and a weight gain rate of 30.3 g/day
