  In a bivariate analysis (sometimes referred to as univariate – see Box 1 below) there is only one independent and one dependent variable. In a multivariable analysis there are: One dependent variable and Two or more independent variables.

  Step 1: Use univariate analysis to identify important covariates – the ones that are at least moderately associated with response. • One covariate at a time. • Analyze contingency tables for each categorical covariate. Pay particular attention to cells with low counts. May need to collapse categories in a sensible fashion.

  As in univariate logistic regression, let ˇ(x) represent the probability of an event that depends on pcovariates or independent variables. Then, using an inv.logit formulation for modeling the probability, we have: ˇ(x) = e0 + 1 X 1 2 2::: p p 1 + e 0 + 1 X 1 2 2::: p p So, the form is identical to univariate logistic regression, but now with ...

  1: Univariate Logistic Regression I To obtain a simple interpretation of 1 we need to find a way to remove 0 from the regression equation. I On the log-odds scale we have the regression equation: logODDS(Y = 1) = 0 + 1X 1 I This suggests we could consider looking at the difference in the log odds at different values of X 1, say t+z and t ...
