...the maximization procedure 1000 times and I should always obtain the same estimate of the parameter (equal to the simulated one) but, instead, i obtain different results (the likelihood function shouldn't be flat). Does anybody has experience with the optimize procedure?

...omeone tell me some indices to see the goodness of fit in multilevel modelling? I'm using the lmer function, and I want to know if my model fit well my data. I actually want to justify the use of multilevel model instead the classical one. Hope someone can help me. Thank you. Greetings Chiara

...of items to replace is not a multiple of replacement length . I am changing the scale parameter but I still get the same warnings. I have no idea of the meaning of the warnings, I would be grateful if you could help. Is it possible to find a C code of th ebackfitting algorithm?

I was wondering whether there is an R version of the S function interp. Would anybody be able to help. Thank you in advance. Chiara

...sions, they seem to be exactly the same and the coefficient which should refer to the dummy variables is not reported. My guess is that I did not actually implement the covariates in the regression, but I cannot understand where is the problem. Any suggestion? Thank you in advance.

I made a dataframe, called "DATA", with two Columns: A, that is my response, and it is "class numerical". B, that defines the different levels of my factor, and it is "class factor". If I want to use a fixed effect model, I know that the formula I have

By looking at the function, I understood that an IV regression is actually implemented automatically by the function but I did not understand where to specify the instrument to be used to clear my treatment variable from endogeneity. The command I used to
