Proportional hazards models are a class of survival models in statistics. Survival models relate the time that passes, before some event occurs, to one or more covariates that may be associated with that quantity of time. In a proportional hazards model, the unique effect of a unit increase in a covariate is multiplicative with respect to the hazard rate. For example, taking a drug may halve one's hazard rate for a stroke occurring, or, changing the material from which a manufactured c…
WebGeneralized Linear Models. There is an entire sub-field of statistical modeling called generalized linear models, where the outcome variable undergoes some transformation to enable the model to take the form of a linear combination, i.e. f (E[Y]) = β 0 + β 1 X 1 +…+ β k X k..
