Assessing significance of slopes and interactions in mixed models
How do I test not only for differences among slopes, but also that the slopes are different from zero (significant) in a linear mixed effects model with 1 continuous and 1 categorical (2 level) variables, and two random effects. In the Parameter Estimates output below I see that I have a significant interaction between tissue type [MSC] and lnSe. Meaning that the slope for MSC is different from t...
