Investigation of statistical relationships between quantities describing bone architecture, its fractal dimensions and mechanical properties

Vol. 12, no. 4

The paper presents linear, logarithmic and exponential regression tabecular bone indices, fractal dimensions and strength. The analysis of the above parameters was supported by determining non-parametric correlation coefficients: Spearman’s ń, gamma and Kendall’s ô. The principal components’ analysis (PCA) was also performed in order to reduce the number of indices describing the variance in the data set. The analysis showed the most independent indices: lacunarity (ëm, ëmin, ëmax), BMD, Conn.D., SMI, DA, ńA and age.
