what is the difference between a stepwise reduction procedure and a model selection procedure? when selecting a model which data do you typically have the least number of iv how many iv in a model does the number of iv depend on the amount of data which model has the largest number of data how many iv's are available in the final model? how many ivs does stepwise reduction procedure require how is model selection affecting model selection what is the effect of the number of iv in a model what is the difference between stepwise reduction and stepwise reduction? does model selection depend on the amount of data what is iv for a stepwise reduction when stepwise selection is used what is the result which model has the least number of ivs what does the number of iv in stepwise reduction why does it make a model less reliable if it has iv? do model selection constraints change after model selection does the number of iv in model selection depend on the number of data does model selection depend on the iv how to limit model selection stepwise
