Linearity/Mean zero assumption - Means that the expected value (deviances) of errors is zero. This leads to difficulties in estimating B0 and means that our model does not include a necessary systematic component Constant variance assumption - Means that it cannot be true that the model is more accurate for some parts of the population, and less accurate for other parts of the populations. This can result in less accurate parameters and poorly-calibrated prediction intervals. response (dep...
