Re: [R] Testing significance of individual regression slopes

You can't if I understand correctly: there is no individual subject regression coefficient, only a variance component for a random subject intercept. Do you mean that you want to "test" whether that component is nonzero ?(It is, of course). If so, IIRC, lmer eschews such tests for technical reason

[R] Testing significance of individual regression slopes

2016-09-27 Thread Patzelt, Edward
Hi R-help, I have an lmer logistic regression with a within subjects IV and subject as a random factor: model <- lmer(optimal_choice ~ level_one_value_difference + (1|subid), data = dat) What I want is to test if the individual subject regression coefficient is significantly different from 0.
