但我也出现了问题，放进去之后图像倒U型不明显。请问变量值的均值和标准差是填0和1还是实际跑出来的值？
A note about standardisation of variables. Standardised variables are those that are both centred around zero and are scaled so that they have a standard deviation of 1. Personally, I prefer to use these when testing interactions because the intepretation of coefficients can be slightly simpler. Some authors, such as Aiken and West (1991), recommend that variables are centred (but not standardised). The results obtained should be identical whichever method you use. If you prefer to analyse centred (but not standardised) variables, you can use the "unstandardised" versions of the Excel worksheets, and enter the mean of the variables as zero.
就像这个图一样，大部分有关调节效应图绘制的教程都是调节线性关系而非曲线关系，所以想请问各位大神这种曲线关系的调节效应图应该如何绘制？
