Runs the stepwise regression on the output received from
top models of the consolidated output of different GDS runs. With
n
being the number of runs, the stepwise regression starts
with at most (n-3)
selected effects from the previous step. The
remaining effects from the previous step as well as all main effects are
given a chance to enter into the model using the forward-backward stepwise
regression.

A list returning the selected effects as well as the corresponding important factors.
a vector with effects' names corresponding to the starting model.
a vector with effects' names corresponding to the remaining main effects and other effects that needs to be explored with stepwise regression.

main effects.
a matrix of m choose 2

interactions.
a vector of n
responses.
the p-value cutoff for the most significant effect to enter into the stepwise regression model
the p-value cutoff for the least significant effect to exit from the stepwise regression model
a string with either none
, or weak
, or strong
. Denotes
whether the effect-heredity (weak or strong) should be embedded in GDS-ARM.
The default value is none
as suggested in Singh and Stufken (2022).
