R-Squared

Adj R-Squared

Pred R-Squared

**A.**the query is, can we ignore/live-with poor or low Pred R-Sq.

1) during screening designs(Res-II or Placket Burman Design),

2) there is an analysis of DOE through option for historical data ,

in both cases, we are essentially looking for not a model, but JUST co-efficient and their magnitude (apart from the main effects)

**B.**for exploratory work, can we do work with p-value on marginally higher side (approx 0.06-0.1 vs 0.05 )
