Abstract
The present invention relates to a survival curve generating system using an exponential function and a method thereof. According to the present invention, a survival curve generating system includes a data collection unit that collects data obtained from a clinical trial for cancer, a survival curve construction unit that generates a survival curve by using a survival curve model including multiple exponential functions based on the collected data, and an analysis unit that calculates a relative ratio of one exponential function included in the survival curve model, obtains intensity from a sigmoid curve derived using the relative ratio, and separates a patient group based on the intensity.
