Model comparison.

Optimal number of functional principal components, proportion of variance explained, Akaike Information Criterion (AIC), Bayesian Information Criterion (BIC), multiple correlation coefficient (r), and F statistic with associated p-value for each model.针对每个模型，包含其函数主成分最优数量、解释方差占比、赤池信息准则（Akaike Information Criterion, AIC）、贝叶斯信息准则（Bayesian Information Criterion, BIC）、多重相关系数（multiple correlation coefficient, r）以及带有伴随p值的F统计量。
