what model is the best stepwise approach how does a stepwise model work does an forward stepwise approach guarantee a global optimum highest possible R2 model which approach guarantees optimum model building is forward stepwise optimal or optimum highest model rated variables what model is best if a stepwise approach is used? what is the stepwise approach what is the highest possible r2 what is stepwise approach to model what is the highest possible model what is the highest possible model r$2 what is the highest model value if the stepwise approach? what is the highest model in forward stepwise model which stepwise approach guarantees global optimisation what stepwise approach guarantees a global optimum? highest possible r2 model what is the highest possible r2 which approach produces the highest value?
