Multivariate analyses are used to study the structural patterns of ridge counts of fingers. There is a significant difference between the ridge counts of two hands, chiefly due to the first and fourth fingers. There is asymmetry in the covariance matrix of the ridge counts. The correlations between fingers are significant and the decrease in correlation with increasing distance between fingers is not significant.

Riassunto

RIASSUNTO

Viene usata un'analisi multivariata per lo studio delle caratteristiche strutturali dei conteggi dermatoglifici digitali. Vi è una differenza significativa fra i conteggi delle due mani, prevalentemente a causa del primo e del quarto dito. Vi è asimmetria nella matrice di covarianza dei conteggi. Le correlazioni fra dita sono significative e la riduzione di correlazione con l'aumento della distanza fra dita non è significativa.

Résumé

RÉSUMÉ

Une analyse multivariée est utilisée dans l'étude des caractéristiques structurelles des comptes des crêtes digitales. Une différence significative existe entre les comptes des deux mains, surtout à cause du premier et du quatrième doigt. Il y a asymétrie dans la matrice de covariance des comptes. Les corrélations entre doigts sont significatives et la réduction des corrélations avec l'augmentation de la distance entre les doigts n'est pas significative.

Zusammenfassung

ZUSAMMENFASSUNG

Zur Untersuchung der Strukturmerkmale bei den Zählungen der Fingerlinien wird eine multivariierte Analyse angewandt. Die Zählungen der beiden Hände sind, hauptsächlich aufgrund des ersten und des vierten Fingers, wesentlich verschieden. Es besteht eine Asymmetrie in der Kovarianz-Matrize der Zählungen. Die Korrelationen zwischen den einzelnen Fingern sind wesentlich, während die Verminderung der Korrelation bei zunehmender Distanz zwischen den Fingern nicht bedeutsam ist.
