I'm trying to do some modelling of time to event data and for various reasons, the Aalen additive model seems promising.

I'm using the aareg function in the survival package, but I'm struggling to find much literature (that isn't paywalled) to get more of a feel for the procedure.

Does anyone have any suggestions of some anything reasonably in depth, but accessible to someone without expert level knowledge of newer survival analysis techniques?


Klein, J. P. & Moeschberger, M. L. (2003). Survival Analysis: Techniques for Censored and Truncated Data. New York: Springer, 2nd ed.

Chapter 10 is about Additive Hazards Regression Models. Section 10.2 specifically deals with Aalen’s Nonparametric, Additive Hazard Model.

A couple of other references:

Aalen, O. (1980). A model for nonparametric regression analysis of count- ing processes. In Mathematical Statistics and Probability Theory, W. Klo- necki, A. Kozek & J. Rosiński, eds., vol. 2 of Lecture Notes in Statistics. New York: Springer, pp. 1–25.

  • $\begingroup$ Ocram, many thanks for your answers, and I might need to just expense one of the books you've listed. However, I'd advise against offering to breach copyright on a public forum, much as I appreciate the gesture. $\endgroup$ – Simon Hayward Apr 1 '14 at 8:00
