当我做
WEIGHT BY wGEDA09pop.
FREQUENCIES VARIABLES=sex
/ORDER=ANALYSIS.
在 SPSS 中，我得到了 48.5% 的男性 (1) 和 51.5% 的女性 (2)。
如果我做
round(prop.table(xtabs(test[,2] ~ test[,1], test)),3)
我得到了 49,2% 的男性 (1) 和 50,8% 的女性 (2) 测试数据集 47,8% 的男性和 52,2% 的女性。
有人知道他们为什么不同，以及我如何在 SPSS 中设置权重，以便权重对所有程序都有效，例如 pca ...？
非常感谢。多米尼克
