It is shown that there is a possibility to increase the power of statistical processing through the use of several well-known statistical tests, through the neural network combining their private decisions. Contains tables of formulas promising statistical criteria that complement already used statistical tests. Considered the influence of quantization errors caused by the small amount of experience in the test sample. Proposed to raise the reliability of the estimates due to the digital smoothing of histograms with uniform quantization step. Shows the tables and nomograms to assess the reduction in the probability of errors of the first and second order transition to multivariate statistical analysis of biometric data.
