Scientific paper

A new statistical method to obtain a formal value of the deceleration parameter q0 in Friedmann-Lemaître models is outlined; no evolution is assumed. With a sample of 116 brightest galaxies of nearby Abell clusters, one obtains q0 = -1.2±0.6. With respect to least-square fit methods in the Hubble diagram, this approach has the advantage of being independent of the luminosity function and of selection effects such as the Malmquist effect and the Scott effect, furthermore these effects can be quantitatively estimated.
