how to tell whether a linear model is subpopulation which model of linear regression does a phantom data set contain what is the degree of freedom to use a glm for logistic regression what is aic in spss what degree of freedom does spss use? what is the degree of freedom in spss for a generalized logistic regression model what is the aic of a glm model in spss mean which model contains common values? glm spss why do you think the aic is smaller on a glm model with only one predictor? how to tell whether the spss model is a subpopulation? what is the aic for spss why is aic different than a glm what is the degree of freedom for a glm model why would i expect to get similar results in spss? does pbss work with spss why are aic estimates different than dif for a spss model why does spss treat data as subpopulations why do sputs use subpopulations spss models that ignore subpopulations aic = degree of freedom
