www.dc.state.fl.usdata. The analyses of factor significance are conducted using Cox models (proportional hazards regression) of the same data. The analysis used a 5% level of significance to determine which factors to include, and a stepwise selection routine for determining the order of importance. The correlations between factors were considered during
