Atypical indices in human paleontology

For a normally distributed variable, the index of atypicality associated with a measurement of that variable is defined as the probability of finding a result closer to the mean of the reference population than the one actually observed. The method extends straight forwardly to multivariate situations, thus providing a joint interpretation of multiple observations recorded on the same subject. In human palaeontology, atypicality indices allow to analyze and to compare the results obtained from variables closely associated with specific traits of the morphology. We briefly outline the principle of the method and give a computer program to carry out the calculations. Finally, we apply the use of univariate and multivariate atypicality indices to data recorded on 53 Upper Palaeolithic skulls

Graphic normality test in human paleontology

In human palaeontology, samples are generally collections of objects gathered according to morphological criteria and their statistical analysis usually calls for caution because of the relatively small number of objects. Testing normality for such samples is a critical problem. The procedure suggested by Filliben, however, is particularly suitable for small to moderate sample sizes. Moreover, it provides a graphical presentation of the data that permits to locate each object within the distribution range. We briefly review the principle of the method and give a computer program to carry out the necessary computations and plot. Finally, we illustrate the method by studying the distribution of the maximum length and the maximum breadth for a sample of skulls of the Upper Palaeolithic
