We consider the multivariate distribution of amino-acids coding for proteins in Open Reading Frames (ORFs). An appropriate statistical model of this distribution might throw some light on the interdependency of the 20 amino-acids and contribute to the problem of verification of known ORFs (At the date 3. April 2008 only 71.02\% of known ORFs were verified). From a graphical analysis od the data we...
By intrinsic dimensionality of a data set we mean the smallest number of base vectors which permit to reconstruct the considered set. Nowadays we obtain very huge data sets, which are computationally demanding. Therefore we look for some representative data vectors (prototypes) which might yield an insight into the data and be used for a (preliminary) data analysis. Let D of size n times d denote...
