Webb14 apr. 2024 · If two values (x and y) are proportionally related, one can express their relationship in the formula: y = x * k where: y = the dependent value or range x = the independent value or domain k = the constant of proportionality To find the constant of proportionality, one divides both sides of the equation by x and gets: y/x = k Attachments … WebbIf the predictor satisfy the proportional hazard assumption then the graph of the survival function versus the survival time should results in a graph with parallel curves, similarly the graph of the log (-log (survival)) versus log of survival time graph should result in parallel lines if the predictor is proportional.
