Run regression analysis without excluding variables.

[Abdus Salam]

Dear Experts;

  I am facing a problem in one of my regression model; To developed that model I have one dependent variable which shows proportion of initiate on medicine and 23 attributes variable as an independent variables; when I run simple linear regression then some of the attributes excluded so to get rid of that excluded variable I run the regression in Enter method and take the attributes block wise. Now my question: is there any other way to get rid of that type of excluded variables. I can run also first time factor analysis with in that attributes and then
  Run also regression with that factor solution; but client needs 23 attributes derived Importance. So is there any other option to run the regression analysis without using block.

  Thanks for any of your’s quick response.
