The pancreas has many functions related to digestion and the regulation of blood sugar levels. Pancreatitis is a disease caused by inflammation of the pancreas..
causes as censoring events, the concept of relative survival was developed by comparing the observed survival probability of a group of cancer patients with the survival of a âsimilarâ cancer-free group. Relative survival is defined as the ratio of the observed survival (all cause survival) of a cohort of cancer patients to the expected survival of a comparable set of cancer free individuals.
In this model, it is assumed that the survival times (or log survival times) come from a normal distribution; the resulting model is basically identical to the ordinary multiple regression model, and may be stated as: t = a + b1*z1 + b2*z2 + ...+ bm*zm. where t denotes the survival times.he life table technique is one of the oldest methods for analyzing survival (failure time) data (e.g., see Berkson & Gage, 1950; Cutler & Ederer, 1958; Gehan, 1969). This table can be thought of as an enhanced frequency distribution table.
