I have a thesis in which I have to do survival analysis. In which I have to find multiple prognostic factors.

Usually it is done by applying Univariate analysis in which many factors are analyzed individually and if they get significant value then they are assessed in multivariate analysis. For example we want to assess age, gender, tumor size, socio-economic status.

For this we have to analyze all of them in univariate analysis individually and suppose three of them get significant result,we will then analyze those three in multivarate analysis.

My question is how to use Univariate analysis in SPSS using 1 or 2

1) Analyze>survival>Kaplan-Meier

2) Analyze>Survival>Cox Regression and using only one covariate at a time for Univariate analysis

Thanking you
