Type III (Wald) Tests
The Type III (Wald) Tests table in this example is
a further breakdown of the variation due to MODEL.
The DF for Model are broken down into terms
corresponding to the main effects for YEAR,
TYPE, and PERIOD, and the interaction effects
for TYPE*YEAR, YEAR*PERIOD, and TYPE*PERIOD.
The composite explanatory power of the set
of parameters associated with each effect
is measured by the Chi-Square statistic.
The p-value corresponding to each Chi-Square statistic
is the probability of observing a statistic of equal or greater
value, given that the corresponding parameters are all 0.
