ON INVESTIGATION OF LONGITUDINAL MODELS UNDER THE UNBALANCED PANEL DATA FOR SMALL DATA SIZES INDUCED BY MISSINGNESS

Tables 1, 2, and 3 represent estimates of Mean Square Error (MSE) for different sample sizes (i.e., N = 20, 25, and 30), while Tables 4, 5, and 6 show estimates of Mean Absolute Error (MAE) for different sample sizes (i.e., N = 20, 25, and 30)

表1、表2及表3展现了不同样本量（即N=20、25和30）下的均方误差（MSE）估计值，而表4、表5及表6则呈现了针对不同样本量（即N=20、25和30）的均绝对误差（MAE）估计值。
