The article provides practical steps toward performing Cox analysis and interpreting the output of SPSS for Cox regression analysis. Along with it, the article touches on the test to be performed before performing a Cox regression analysis and its interpretation. The SPSS code is: COXREG Time /STATUS=Failed(1) /PATTERN BY Variable /CONTRAST (Variable)=Indicator /METHOD=ENTER Variable /PLOT SURVIVAL HAZARDS LML OMS /PRINT=CI(95) /CRITERIA=PIN(.05) POUT(.10) ITERATE(20).

• The exponential function of the … Cox Regression builds a predictive model for time-to-event data. The model produces a survival function that predicts the probability that the event of interest has occurred at a given time t for given values of the predictor variables. The shape of the survival function and the regression coefficients for the predictors are estimated from observed The steps for interpreting the SPSS output for a Cox regression 1. In the Variables in the Equation table, look at the Sig. column, the Exp (B) column, and the two values under 95.0% 2. The Sig. column shows the p -value associated with that variable in the model.

SPSS ENTER Regression - Output. In our output, we first inspect our coefficients table as shown below. Some things are going dreadfully wrong here: The b coefficient of -0.075 suggests that lower “reliability of information” is associated with higher satisfaction. However, these variables have a positive correlation (r = 0.28 with a p-value Cox regression (or proportional hazards regression) is method for investigating the effect of several variables upon the time a specified event takes to happen. In the context of an outcome such as death this is known as Cox regression for survival analysis. A previous article explained how to interpret the results obtained in the correlation test.
