1997A&A...321...10W Influence of a partial incompleteness of the sample on the determination of the Hubble constant. Witasse O., Paturel G. Abstract. This paper presents a study of the Malmquist bias effect in the determination of the Hubble constant from the method of "sosies" (look- alike) galaxies. It is shown that a bias appears when a partial incompleteness exists in the sample. A new method, based on the use of the completeness curve, is proposed to correct for such a bias. After this correction, the Hubble constant drops of about 20% just because of the existence of the partial incompleteness. From the present results and on the acceptance of the distance modulus of primary calibrators, the value of the Hubble constant would be: H_0_=~60km/s/Mpc with an internal statistical error of about 2km/s/Mpc. Key words: distance scale - methods: data analysis - galaxies: general
