【How-to】What does glmm mean - Howto.org

In R, using lm() is a special case of glm(). lm() fits models following the form Y = Xb + e, where e is Normal (0 , s^2). glm() fits models following the form f(Y) = Xb + e. However, in glm both the function f(Y) (the ‘link function’) and the distribution of the error term e can be specified.
