Quantum superposition of the discrete spectrum of mathematical correlation molecule status for small samples of biometric data

Introduction. The study promotes to decrease a number of errors of calculating the correlation coefficient in small test samples. Materials and Methods. We used simulation tool for the distribution functions of the density values of the correlation coefficient in small samples. A method for quantization of the data, allows obtaining a discrete spectrum states of one of the varieties of correlation functional. This allows us to consider the proposed structure as a mathematical correlation molecule, described by some analogue continuous-quantum Schrodinger equation. Results. The chi-squared Pearson's molecule on small samples allows enhancing power of classical chi-squared test to 20 times. A mathematical correlation molecule described in the article has similar properties. It allows in the future reducing calculation errors of the classical correlation coefficients in small samples. Discussion and Conclusions. The authors suggest that there are infinitely many mathematical molecules are similar in their properties to the actual physical molecules. Schrodinger equations are not unique, their analogues can be constructed for each mathematical molecule. You can expect a mathematical synthesis of molecules for a large number of known statistical tests and statistical moments. All this should make it possible to reduce calculation errors due to quantum effects that occur in small test samples.
