Hello, How do I fit a mixed effect model with no intercept using lmer()? Is the following syntax correct? lmer(y ~ -1+x1+x2+(-1+x1+x2|id), data=dt) Thanks, Julia -- View this message in context: http://n4.nabble.com/lmer-how-to-lmer-with-no-intercept-tp990493p990493.html Sent from the R help mailing list archive at Nabble.com.

An alternative, which I prefer, is lmer(y ~ 0 + x1 + x2 + (0 + x1 + x2|id), dt)
