can anyone tell me how can i control the method of estimation (i.e. scoring
method or Newton raphson method) in glm and compute deviance function ?

effects, one subject specific, and one observation specific. Thus if we
count random effects, there are more parameters than observations. When I
try to run the following code, I get an error saying: "Error in

Is it true that there is no way to fit such a model in an ML analysis? In
