Stanley E. Porter and Matthew Brook O’Donnell 38 Of the eleven interactive systems analyzed, in only one set of semantic choices does it appear that choice of verbal aspectual semantic features is affected by other verbal semantic choices. In interactive system test 6, the choice of +projective results in a skewed distribution of +perfective over –perfective, whereas system 2 for ASPECT1 on its own has an equiproba- ble distribution. Other than this one instance, there is no statistical evi- dence that choice of semantic features regarding verbal aspect are affected by other verbal semantic choices in the Greek verbal network. 6. Conclusions This study has accomplished a number of goals. The first is that it has introduced Hallidayan statistical analysis into study of the Greek of the New Testament, in particular statistical analysis of the Greek verbal net- work. Halliday’s suggestive comments have proved a fertile ground for developing a set of statistical tests for the Greek verbal network, as de- scribed and graphically displayed in the Greek verbal network of Porter in his Verbal Aspect. The second accomplishment is that this study has led to further development of this verbal network, by adding sets of systems for CAUSALITY, NUMBER and PARTICIPATION, and their respective sub-systems (Appendix B, below, names these sub-systems for the sake of clarity, although they are not all so designated above or in the system network in Appendix A). These add important dimensions to the network and ena- ble this diagram to represent the complete Greek verbal network. Although some of the systems may require further development in the light of subsequent research, at least at this point they can be entered into discussion as part of an integrated verbal system network. The third accomplishment is to study the statistical probabilities that attach to the various systems within this network of Greek verbal structure. The Hallidayan framework, with necessary modifications, has been used, label- ling the statistical frequencies in terms of equiprobable or skewed distri- butional results. These systems have been studied and analyzed from seve- ral different perspectives. The most obvious perspective is to analyze the distributional probabilities of each of the individual systems over the whole of the Greek of the New Testament. Another is to analyze these dis- tributional patterns over the various sub-corpora that make up the Greek New Testament. The results of these studies have indicated that initial predictions made on the basis of Porter’s previous analysis have in vir- tually all instances been confirmed through this statistical study. The last accomplishment is to select for further analysis a number of interactive systems in the network, especially those that involve choice regarding semantic features of the aspectual systems, to determine how choice of verbal aspect may or may not be affected by selection of other semantic features within the Greek verbal network. The results have indicated that
