请问一下这个excel表格里面simple slopes analysis 下面要填variance of coefficients of IV/interaction/IV and interaction是什么东西？在spss里面没有看到这个系数，不知道怎么算。有大神指点一下迷津吗~~~感激不尽

不好意思，应该是简单斜率分析（手快打错了）

To run simple slope tests, you will also need to request the coefficient covariance matrix as part of the regression output. If you are using SPSS, this can be done by selecting "Covariance matrix" in the "Regression Coefficients" section of the "Statistics" dialog box. Note that the variance of a coefficient is the covariance of that coefficient with itself - i.e. can be found on the diagonal of the coefficient covariance matrix.
