Hi all,

   I used the function 'glm' to perform logistic regression, and then use 'summary' to display the fitting result. There are 'z value' and 'Pr(>|z|)'

  Do they simpily represent the result of 'z test' ? as I perform the 'z test' for a particular variable following the definition, it yields a different result.
