SPSS Stepwise Regression - Model Summary SPSS built a model in 6 steps, each of which adds a predictor to the equation. While more predictors are added, adjusted r-square levels off : adding a second predictor to the first raises it with 0.087, but adding a sixth predictor to the previous 5 only results in a 0.012 point increase. But why does SPSS come up with a = 34.3 and b = 0.64 instead of some other numbers?
