The table also includes the test of significance for each of the coefficients in the logistic regression model. For small samples the t-values are not valid and the Wald statistic should be used instead. Wald is basically t² which is Chi-Square distributed with df=1. However, SPSS gives the significance levels of each coefficient. In statistics, the Wald test (named after Abraham Wald) assesses constraints on statistical parameters based on the weighted distance between the unrestricted estimate and its hypothesized value under the null hypothesis, where the weight is the precision of the estimate. The Wald test ("Wald" column) is used to determine statistical significance for each of the independent variables.

This paper investigates a modified version of the Wald test of regression disturbances. The Monte Carlo results in the context of testing for MA(1) regression disturbances show that the modified Wald tests always have monotonic increasing power
Whenever a relationship within or between data items can be expressed as a statistical model with B is the coefficient, SE is the standard error corresponding to B, Wald is the chi-square distributed test statistic, and Sig. is the corresponding p -value. Note that the odds ratios are simply the exponentiated coefficients from the logit model. For example, the coefficient for educ was -.252. The odds ratio is exp Forward Selection (Wald).

Backward Elimination (Conditional). Backward stepwise selection. Like the LM test, under the null hypothesis that the model parameters are zero in the population, and with an a priori selection of parameters to test, the Wald test asymptotically follows the χ 2 distribution with either 1 df or as many df's as there are parameters being tested (see e.g., Satorra, 1989). A Wald test is used to test the statistical significance of each coefficient (b) in the model. A Wald test calculates a Z statistic, which is: This z value is then squared, yielding a Wald statistic with a chi-square distribution.
l. Wald and Sig. – These columns provide the Wald chi-square value and 2-tailed p-value used in testing the null hypothesis that the coefficient (parameter) is 0. If you use a 2-tailed test, then you would compare each p-value to your preselected value of alpha. Coefficients having p-values less than alpha are statistically significant.
