Logistic Regression : Wald Chi-Square
Wald Chi-Square = Square of (Coefficient Estimate / Standard Error)
Important Note :

  1. In SAS, PROC LOGISTIC returns Wald Chi-Square value by default.
  2. In R, glm package for logistic regression returns z-statistics. We need to take square of z-statistics to calculate wald chi-square.
