Perform Buckley-James Estimation

Check this box to perform survival analysis using the specified model and assuming some of the observations are right-censored.

Estimation is performed by iteratively fitting the model with an updated dependent variable that replaces censored observations with estimates of their true time-to-event values.

The method is a generalization of the original regression algorithm of Buckley and James (1979) ¹ as expanded upon by Glasson (2007, RMIT PhD Thesis).

Note : You must specify the time-to-event dependent variable (this variable can be log -transformed) as the Dependent Variable on the General tab. You must also specify the Censor Variable and other options on this tab.

To Perform Cross Validation Model Comparison:
