how to use nlmefit to multilevel regression (mixed effect) model

2 visualizzazioni (ultimi 30 giorni)
I have the following data:
X - column vector of n predictor values
Y - column vector of n responses
G - column vector of n values defining group membership in one of g groups
The model to be fitted is
y_ij = b_0 + b_1*.x_i + u_j
The values y_ij are presented in the vector Y for the corresponding values of the vector X.
How can I arrange the calling the nlmefit function, especially FUN parameter.

I'm afraid I can't code up your specific problem for you. I was hoping that the simple example that Tom posted would give you a hint.
There is also a thorough example in the documentation of nlmefit(). Have you looked it and tried to understand it?

Yes, of course. The first place that e look for solution was the documentation....
I'll try to manage the problem and I'll post the solution after that.
