Effects of omitting a covariate in Poisson models when the data are balanced.
Can J Stat 2000 Apr-Jun; 28(2):439-445
The authors show that for balanced data, the estimate of effects of interest and of their standard errors are unaffected when a covariate is removed from a multiplicative Poisson model. As they point out, this is not verified in the analogous linear model, nor in the logistic model. In the first case, only the estimated coefficients remain the same, while in the second case, both the estimated effects and their standard errors can change.
