why do we use the collapse dimension why do I need to combine dimensions in a two way anova model how many models are there in the collapse dimension what dimension should I converge the coefficients of anova what is the collapse dimension of a model? why do i need to compare dimensions how many coefficients in anova what is a collapse dimension how to find the coefficients of a model how do i find the coefficient in a model? a.Collapse dimension definition how do you find the coefficient of a model how to determine if a model is a collapse dimension which dimension is a collapse which dimension will a model coefficient be collapsed which model measures the collapse? what does the collapse dimension mean in a model which condition can result in a decrease in the model coefficient on condition b? which model has coefficients of collapse how does a collapse dimension affect the coefficient of a model what is the collapse model
