Hello,
I want to specify a linear regression model in which the metric outcome
is predicted by two factors and their interaction. glm() computes
effects for each factor level and the levels of the interaction. In the
case of singularities glm() displays "NA" for the corresponding
coefficients. However, svyglm() aborts with an error message. Is there a
possibility that svyglm() provides output for coefficients without
singularities like glm()?
Thank you very much,
Sebastian Weirich
