我试图对一些数据运行方差分析,但它给了我以下错误:
Call:
aov(formula = speaker ~ CoG * skewness * kurtosis, data = total)
Error in levels(x)[x] : only 0's may be mixed with negative subscripts
In addition: Warning messages:
1: In model.response(mf, "numeric") :
using type="numeric" with a factor response will be ignored
2: In Ops.factor(y, z$residuals) : - not meaningful for factors
我试图看看三个变量 CoG、偏度和峰度对说话人的预测效果如何,以及它们在说话人之间是否显着。我的数据副本可以在这里找到:

谁能帮助解释错误在说什么以及它发生在哪里?
