Intuition for cumulative hazard function (survival analysis)

WebThe Nelson-Aalen estimate of the cumulative hazard is usually used for estimates of the hazard and often the cumulative hazard. If the hazards of the three groups are proportional, that means that the ratio of the hazards is constant over t. We can test this using the ratios of the estimated cumulative hazards, which also would be proportional.
