The method of statistical parallaxes is applied to a sample of 262 Rrab RR Lyr type variables with published photoelectric photometry, radial velocities, abundances and with known absolute proper motions. The proper motions are adopted from the Hipparcos, PPM, NPM1, and the Four-Million Catalog (Volchkov et al. 1992, Ed. by A.P.Gulyaev and V.V. Nesterov, Mosk. Gos. Univ., Moscow, p. 67) and in the case the last three catalogs are reduced to the Hipparcos system. The parameters of the velocity distribution of halo (U0, V0, W0) = ( -9+/-12, -214+/-10, -16+/-7) km/s and thick-disk (U0, V0, W0) = (-16+/-8, -41+/-7, -18+/-5) km/s RR Lyrae subsamples are inferred as well as the intensity-averaged absolute magnitudes of the corresponding populations: = 0.77+/-0.10 and = +1.11+/-0.28 for halo and thickdisk objects, respectively.
