Bias of the Hubble Constant Value Caused by Errors in Galactic Distance Indicators

The bias in the determination of Hubble parameter and constant modern Universe is discussed. It could appear due to statistical processing data on redshifts galaxies estimated distances based some relations with limited accuracy. This causes a number effects leading either underestimation or overestimation when using any methods processing, primarily least squares method (LSM). value underestimated whole sample; sample constrained by distance, especially from above. Moreover, it significantly overestimated selection. exceeds values erro ofr calculated LSM formulae. These are demonstrated both analytically Monte Carlo simulations, which introduce deviations velocities original dataset described law. characteristics similar real observations. Errors up 20%.
