Do Government Payments Influence Farm Business Survival? [PDF]

open access: yes
Using a unique farm-level panel data set derived from three U.S. Agricultural Censuses, we estimate a Cox proportional hazard model to examine the effect of direct government payments on the survival of farm businesses, paying particular attention to the

Fitting the Cox proportional hazards model to big data

open access: yesBiometrics
AbstractThe semiparametric Cox proportional hazards model, together with the partial likelihood principle, has been widely used to study the effects of potentially time-dependent covariates on a possibly censored event time. We propose a computationally efficient method for fitting the Cox model to big data involving millions of study subjects ...
