Rytų aukštaičiai panevėžiškiai: klasterinė analizė ieškant tarmiškumo
Eastern Aukštaitian of Panevėžys: Cluster Analysis in Search of Dialecticism

Summary/Abstract: This paper aims to test the appropriateness of one of the statistical methods – cluster analysis – to determine the similarity of the populated localities of the Eastern Aukštaitian of Panevėžỹs in accordance with the frequency of usage of distinctive dialectal features. Grouping peculiarities that emerged from the analysis of the research areas allow us to create a model to measure the dialecticism and the peripherality of the research areas. 90 minute long recordings of the Eastern Aukštaitian of Panevėžỹs collected from two central – Pasvalỹs (112), Kapčiunai (138) – and two marginal – Bučinnai (52), Stuibriškis (171) – dialectal points were randomly selected for this study. While listening to the recordings, the frequencies of usage of 13 dialectal features of the Eastern Aukštaitian of Panevėžỹs were identified, which were then entered into the SPSS Statistics computer program and the cluster analysis was performed. The results suggest that the cluster analysis model applied in the study is suitable for revealing the grouping patterns of the points of the Eastern Aukštaitian of Panevėžỹs LLA according to the research dimensions. The analysis indicates that the marginal LLA points are not necessarily peripheral – dialectal characteristics are perfectly maintained in them (in Bučiunai, Pasvalỹs and Kapčiunai points of LLA the strong features are better maintained, while the weak ones are better preserved in Stumbriškis).
