how can I compare my linear model to a valid one? why is the aic in linear modeling invalid why are some linear models invalid how is a linear model valid can a linear model be tested on binned data does a linear model have to be completely invalid can a binned logistic model predict an invalid model what model can be tested and used when binned data? can i use bin based binning with a aic how to compare a linear model with an invalid model what is a linear model can you compare a linear model to an invalid one? how to compare a nonlinear model to a technically invalid model? how to compare nonlinear survival with null linear variation can i compare binned data with a nonlinear model can a linear model be tested against an invalid logistic model can i compare a linear model to an invalid model how can a nonlinear model be compared to an invalid model? why do linear models have to be invalid when comparing a model to an invalid model
