Model for a survival outcome based on Gemcitbine patients from ESPAC-3. A generated model with a survival endpoint and a cuymulative hazard function estimated using flexible parametric splines. Data for the model were obtained from the ESPAC-3 trials
gemCFMA model of class 'pscCFM' containg a 'flexsurvreg' model:
cumulative baseline hazard parameters
negative (n=1) or positive (n=2) lymph nodes
tumour grade (1,2 or 3)
log transformed ca19.9
