CONCEPT OF RESILIENCE Resilience: a systems capacity to resist and recover from shock and maintain growth path or community goals Closely related to stability Static resistance to change vs. a process of maintaining desired trajectories Relative measure More or less resilient relative to a reference point
TWO WAYS OF RESILIENCE Hazard rate of a county to experience a downturn Probability of a county to recover from a downturn

COX PROPORTIONAL HAZARDS MODEL Hazard rate for the jth subject h(t|x j )=h 0 (t) exp(x j β x ) where: t is a nongegative random variable denoting the time to a failure event, x j is a vector of multiple predictors, and β x is a vector of regression coefficients. h 0 (t) baseline hazard
