Risk Ratios and meaning the ChiSquare p-valuesHi, I'm trying to understand the meaning of the ChiSquare p-values calculated for Risk Ratios as part of the Proportional Hazards Fit platform. In the attached image, I have run an analysis of the effect of heat shock durations (in hours) and bee origin (feral or managed colonies) on bee survival. The Risk Ratio lead me to this interpretation: the risk of death for bees exposed to 0 h vs. 0.5 h of heat shock is 1.472. But what does P<0.0001 mean?
I am guessing that the what the Risk Ratio p-value is saying is that "the probability of this ratio being equal to 1 is <0.0001"
Is this a correct interpretation?
AnalyticsRe: Risk Ratios and meaning the ChiSquare p-valuesThe way to interpret the p value for a Chi Square, is, what is the probability of the relationship measured is by random chance. Therefore, the finding is highly significant that the data did not happen by chance......something is going on with the Heat shock duration
If you select the Help Tool (?) and click on the Effect Likelihood Ratio Tests table you will get the following definition
Effect Likelihood Ratio Tests
Shows the likelihood ratio chi-square test of the null hypothesis that the parameter estimates for the effects of the covariates is zero.
