Widening the Search

Log-wireless last month (lnwiremon) and Log-wireless over tenure (lnwireten) failed the screening test, but not by much, so you'd like to make allowance for it. You are also interested in obtaining more predictors that pass the significance cutoff. The command syntax used to widen the search is shown here.

SELECTPRED response_01 
  /EXCEPT VARIABLES=custid response_02 response_03
  /SCREENING PCTMISSING=80
  /CRITERIA SIZE=50 SHOWUNSELECTED=10
  /MISSING USERMISSING=INCLUDE.

• Variables with more than 80% missing values, as opposed to the default of 70%, will be dropped from further consideration.
• A maximum of 50 variables with significance values less than 0.05 will be selected.
• The 10 most highly ranked unselected variables will be displayed in the predictor summary table.
