How to interpret output of logistic regression with indicator variable

Question & Answer


Question

I ran a logistic regression analysis with the SPSS Logistic Regression procedure. The predictors included a categorical variable with 4 categories. The "Variables in the Equation" table in the output displays three coefficients for the 3 indicator parameters for this predictor. However, these are preceded by a row with the predictor name in the parameter name column. In this row, there is no B coefficient, S.E., or Exp(B), but there is a Wald value with 3 df and significance. What do the Wald value and significance for this row represent?
