I have the following result from running glm function.

How can I interpret the following values:

  • Null deviance
  • Residual deviance
  • AIC

Do they have something to do with the goodness of fit? Can I calculate some goodness of fit measure from these result such as R-square or any other measure?

Call:
glm(formula = tmpData$Y ~ tmpData$X1 + tmpData$X2+ 
    tmpData$$X2 + tmpData$X3 +
