Log-Minus-Log Plot

Log-minus-log plot

This plot displays the log-minus-log of the survival function, ln(−ln(suvival)), versus the survival time. This particular plot displays a separate curve for each category of History of myocardial infarction, with History of ischemic stroke fixed at One and History of hemorrhagic stroke fixed at None, and is a useful visualization of the effect of History of myocardial infarction on the survival function. As seen in the parameter estimates table, it appears that the survival for patients with one or no prior mi's is distinguishable from the survival for patients with two prior mi's, which in turn is distinguishable from the survival for patients with three prior mi's.
