Hi Cem, I think you can estimate this model using gllamm (see
www.gllamm.org). The variable group identifies the groups. nrf
identifies the number of random coefficients. You should go through the
gllamm manual though as there are many options you can use (e.g., adapt,
nocor, weights, etc.).
* Random effects model with no random slopes
gllamm y x1 x2 x3 x4 x5, i(group)
* Random effects model with multiple random coefficients
gen cons=1
eq inter: cons
eq x1s: x1
eq x2s: x2
gllamm y x1 x2, i(group) nrf(3) eq(inter x1s x2s)

Subject: st: Random Effects Model with Multiple Random Coefficients
Hi all,
I am trying to estimate a model in which multiple variables have random
coefficients. As far as I understand, "xtreg" type commands provide
an estimate for the within-unit variability by decomposing the error
term
into two parts. I haven't seen any command which treats more than one
independent
variable having random coefficient. How can I do it?
