Hi there, I've got a question which is really trivial for sure but still I have to ask as I'm not making any progress solving it by myself (please be patient with an undergraduate student):
I've got a linear model (lm and lmer fitted with method="ML"). Now I want to compare the coefficients (slope, intercept, not the random effects) of both models with a given value (e.g. intercept=0.5, slope=2) to see if the values estimated with the models are significantly different from the given values. I heard about t.test, but I'm sorry to say that I'm not quite understanding what I have to provide as arguments. I would be more than happy if somebody can point out an example similar to the comparison I have to do...
