We present an analysis of observational data on the behavior profiles for two groups of infant langur monkeys (Presbytis entellus): one that had experienced mother loss, and the other, a control group, that had not undergone mother loss. Observations were analyzed in three 2-week time periods: 2 preseparation, 2 separation, and 2 postseparation periods for both groups. The profile analysis application of the multivariate analysis of variance (MANOVA) was employed to test the hypothesis that the two groups had similar patterns of change across time. For each group a vector of 5 difference scores was computed; then MANOVA was used to test the similarity of the mean vectors of difference scores for the two groups. Profiles for the separation and control infants were significantly different for some behaviors, and changes between some time periods were also significant.
我们对两组幼年叶猴（食蟹猴）的行为特征进行了观察数据分析：一组经历了母亲离世，另一组为对照组，未经历母亲离世。观察在三个为期两周的时间段内进行：两组均包括分离前2周、分离期2周和分离后2周。采用多变量方差分析（MANOVA）的轮廓分析应用来检验两组随时间变化模式相似的假设。为每组计算了一个由5个差异分数组成的向量；然后使用MANOVA来检验两组差异分数均值向量的相似性。分离组和对照组幼猴在某些行为上的特征存在显著差异，且某些时间段之间的变化也很显著。
