%description
The stepwise variable selection procedure (with iterations between the
'forward' and 'backward' steps) can be used to obtain the best candidate
final regression model in regression analysis. All the relevant covariates
are put on the 'variable list' to be selected. The significance levels for
entry (SLE) and for stay (SLS) are usually set to 0.15 (or larger) for
being conservative. Then, with the aid of substantive knowledge, the best
candidate final regression model is identified manually by dropping the
covariates with p value > 0.05 one at a time until all regression
coefficients are significantly different from 0 at the chosen alpha level
of 0.05.
