I do not understand how to interpret random slopes from the output of
In the following example the variable "experience.Mom" has a positive estimate at the group level (random slope) which, if I understand correctly is always the case (why??), and a negative effect at the population level. (intervals are over the 0 so no clear effect anyhow).
What does my random slope
Estimate means? How does it influence my outcome variable (Y)?
