Using of LME function in non-replicate data
...nts ( several responses. ) ( it seems describe the data by experimental versus predicted responses plot and residuals plot ) My doubt: The components of variance given by LME function are reliable approximate estimates or this variance are spurious too? ... I thinked that this varinces were calculate by "lack of fit terms". In the case of this variances are wrong, even so can I use the REML coefficients estimates? Thanks in advanced! Regards.

glm with variance = mu+theta*mu^2?
How might you fit a generalized linear model (glm) with variance = mu+theta*mu^2 (where mu = mean of the exponential family random variable and theta is a parameter to be estimated)? This appears in Table 2.7 of Fahrmeir and Tutz (2001) Multivariate Statisticial Modeling Based on Generalized Linear Models, 2nd ed. (Springer, p. 60), where they compare "log-linear model fits to
