What should I include in my code to have the output show how many people are in the yes vs. no group? I know when doing a logistic regression in SPSS, the output automatically includes the # of people in each group on all independent, categorical variables. variables are categorical, you can also use the Loglinear procedure.

The prese There are three different methods of conducting a regression model. Different methods allow researchers to 1) control for confounding variables (simultaneous regression), 2) choose the best set of predictor variables that account for the most variance in an outcome (stepwise regression), or 3) test theoretical models (hierarchical regression). If you specify age_quartiles as a factor (called a categorical covariate in COXREG) rather than a strata variable, you'll again get a single coefficient for S_URAT_07, but also a set of three coefficients that reflect proportionally differing baselines for each level of age_quartiles. The resulting variable is called T_COV_ and should be included as a covariate in your Cox Regression model. Additional Features. The SPSS command language also allows you to specify multiple time-dependent covariates. Other command syntax features are available for Cox Regression with or without time-dependent covariates.

If your dependent variable is continuous, use the Linear Regression procedure. You can use the ROC Curve procedure to plot probabilities saved with the Logistic Regression procedure. Obtaining a Logistic Regression Analysis E From the menus choose: The Cox proportional-hazards model (Cox, 1972) is essentially a regression model commonly used statistical in medical research for investigating the association between the survival time of patients and one or more predictor variables. In the previous chapter (survival analysis basics), we described the basic concepts of survival analyses and methods for The dependent variable is always a dichotomous variable and the predictors (independent variables) can be either continuous or categorical variables.
