It is generally accepted that the dark matter and galaxies are likely distributed differently in space. This difference -- bias -- is very important for reliable predictions of cosmological models. It is often assumed that bias is linear and does not depend on scale. We show that this is not true for all models we study: SCDM, OCDM, LCDM, and tauCDM. The bias appears to be a complicated function of scale, redshift and rotational velocity. We compare our theoretical predictions with APM correlation function and power spectrum, and with clustering of Lyman-break galaxies at high redshift.
