Webb12 jan. 2024 · For example, y = kx is a proportional linear relationship, where k is the constant of proportionality. Nonproportional linear relationships, on the other hand, have a variable ratio between the dependent and independent variables. For example, y = mx + b is a nonproportional linear relationship, where m is the slope and b is the y-intercept. Webb• When hazards are “ﬂat” (e.g., in an exponential model), proportional hazards corre-spond to parallel horizontal lines. • Increasing hazards are necessarily diverging from one another, while • Decreasing hazards are converging. For lots of reasons, it may be the case that hazards aren’t strictly proportional. Consider a few examples:
