# In statistics, do variable screening and variable selection have same meaning?

I thought they had the same meaning.But some paper related to screening would propose new screening method,then it says The resulting model can then serve as an excellent starting point, from where many existing variable selection methods (e.g., SCAD and Adaptive LASSO) can be applied directly from this paper.I think this is just two stage variable selection: first is initial screening,second is commonly called variable selection.
