About
Wald Statistic
The results Scrollsheet with the parameter estimates for the
Cox proportional hazard regression model includes the so-called Wald statistic, and the p level for that statistic. This statistic is a test of significance of the regression coefficient; it is based on the asymptotic normality property of maximum likelihood estimates, and is computed as:
W =
* 1/Var(
) *
In this formula,
stands for the parameter estimates, and Var(
) stands for the asymptotic variance of the parameter estimates. The Wald statistic is tested against the
Chi-square distribution.
