The stability (measured using matrix correlations) of phenetic classifications based on partitions of continuous morphometric data (skeletal measurements from three groups of birds) was compared for ...
Suitable linear transformations for preliminary data analysis are available when data consist solely of continuous variables or solely of binary variables. When mixtures of variables are observed, ...
In spite of their simple description in terms of rotations or symplectic transformations in phase space, quadratic Hamiltonians such as those modelling the most common Gaussian operations on bosonic ...
