The Cox Proportional Hazards Model (aka Cox regression model) is used to analyze the effect of several risk factors (covariates) on survival. The ordinary multiple regression model is not appropriate because of the presence of censored data and the fact that survival times are often highly skewed.
Topics
- Basic Concepts
- Finding Regression Coefficients using Solver
- Finding Regression Coefficients using Newton’s Method
- Determining the Fit of the Model
- Models with Multiple Deaths per Time Period
- Estimating the Baseline Hazard Function
- Residuals
- Real Statistics Capabilities
For those with a calculus background, you can also see the proofs of some of the properties described on the above webpages at

The best statistics cours ever seen for excel user. Thank you very much Professor.
Thanks, Mohamed. I appreciate it.

Dr. Zaiontz, muchas gracias por esta página, realmente como siempre lo he manifestado es muy útil y didáctica.
Dr. por favor que probabilidad hay de agregar en la Regresión Cox, los estadísticos y valor p, de Concordancia, R cuadrado, prueba de máxima verosimilitud, y la prueba de el puntaje logrank ?
Muchas gracias, por su atención.
Dr. Zaiontz, thank you very much for this page, really it is very useful and didactic.
Dr., please what probability do you have to add in the Cox Regression, the statistics and p-value, of Concordance, R squared, maximum likelihood test, and the test of the logrank ?
Thank you very much for your attention.
