您好,请问加权线性与非加权线性有什么区别呢??这一点我很困惑,能帮我解答一下吗?万分感谢!!!
In the case of unequal group sizes SPSS produces two outputs in an ANOVA called weighted and unweighted sums of squares. The weighted sums of squares assumes group sizes are important for example to reflect relative sizes of each group in the general population. Unweighted sums of squares ignore differences in group sizes and compares group means using the same average group size for each group so each group contributes equally to the trend analysis.
