23 Multivariate Regression: Presidential Vote (2008), controlling for Liberalism and Presidential Vote (2004)

24 Appendix: Syntax The following set of commands changes a nominal variable into an ordinal variable. Prespref_2004 had six categories for their presidential preference, including Nader and others. I needed a variable that just included Bush and Kerry. if prespref_2004 = 1 presvote_2004 = 1. if prespref_2004 = 2 presvote_2004 = 2. execute. I wanted a variable that went in the same direction as presvote_2004 and presvote so I recoded ideology to make liberalism coded high. recode ideology (7=1) (6=2) (5=3) (4=4) (3=5) (2=6) (1=7) into liberalism. Here I am adding value labels for liberalism. add value labels liberalism 1 'Extremely conservative' 2 'Conservative' 3 'Slightly conservative' 4 'Moderate' 5 'Slightly liberal' 6 'Liberal' 7 'Extremely liberal' . Here I am creating a three category variable for libealism so the crosstab is easier to understand. recode liberalism (1=1) (2=1) (3=1) (4=2) (5=3) (6=3) (7=3) into liberalismc. add value labels liberalismc 1 'Conservative' 2 'Moderate' 3 'Liberal' . Here I am running a crosstab with presidential vote as the dependent variable and liberalism as the independent variable. crosstabs tables = presvote by liberalism/cells = col /stats = corr. Here I am running a crosstab with presidential vote as the dependent variable and 2004 vote as the independent variable. crosstabs tables = presvote by presvote_2004/cells = col count/stats = corr. Here I am running a correlation between the three variables. corr presvote presvote_2004 liberalism. Here I am running a crosstab with presidential vote as the dependent variable and 2004 vote as the independent variable, controlling for liberalism. crosstabs tables = presvote by presvote_2004 by liberalismc/cells = col /stats = corr. Here I am running a crosstab with presidential vote as the dependent variable and liberalism as the independent variable, controlling for 2004 vote. crosstabs tables = presvote by liberalismc by presvote_2004/cells = col /stats = corr. Here I am running a regression with presidential vote as the dependent variable and liberalism and vote 04 as the independent variables. regr vars = presvote presvote_2004 liberalism / depe = presvote/enter.
