why does not the fitter algorithm converge why does converge r error occur how often does converged analysis occur why the estimation procedure did not converge why does r error occur when adjustment for centre effects why does an estimation procedure not converge which condition is the r error due to the convergent method? convergent problem what is the convergent problem does a fixed effect approach converge with a dummy variable why is the convergent method not applied? which problem is the convergence problem when adjusted for the effect of a lot of centre why does an estimation procedure converge why does fitter(x, y, offset, init, control, weights = weights) not converge? when adjusting for centre effects what is the convergent problem when adjusting for the effect of a lot of centres? how do you converge an estimator why does my r error converge how to solve convergent problem how can a fitter solve the convergence problem of a multicentre trial
