M-Statistic (Kaufman & Remer 1994) - This is a measure of the difference of the distributional peaks. A large M-statistic indicates good separation between the two classes as within-class variance is minimized and between-class variance maximized (M <1 poor, M >1 good). goldsmith psychology

Handle: RePEc:aeg:report:2015-08. WebTesting for separability in the general case is an NP-hard problem. [2] [3] Leinaas et al. [16] formulated an iterative, probabilistic algorithm for testing if a given state is separable. When the algorithm is successful, it gives an explicit, random, representation of the given state as a separable state.

WebThe design of a RBFN in its most basic form consists of three separate layers. The input layer is the set of source nodes (sensory units). The second layer is a hidden layer of high dimension. The output layer gives the response of the network to the activation patterns applied to the input layer. WebThe base function in R to do hierarchical clustering in hclust ().
