| dc.description.abstract | The purpose of screening is to reduce a large set of explanatory variables or factors
to the set of important variables, assuming that there are only a few really important
explanatory variables. In this study, the formula for the pairwise conditional
probabilities and the jointly conditional probabilities for two-stage group screening
designs have been derived. Also the formula for the expected number of incorrect
decisions has been obtained. It has been assumed in this study that the factors
are defective with different a-priority probabilities and the group screening designs
described in this study are those which minimize:
(i) The expected number of runs for a fixed value of the expected number of incorrect
decisions.
(ii) The expected total cost | en |
