The relations between variability and luminosity and between variability and redshift have been investigated by means of ``robust'' statistical estimators, allowing to disentangle the effects of the measurement errors. The results are compared with the corresponding properties of the variability in the B-band for the same sample. An anti-correlation between the R-band variability and the intrinsic luminosity is found, analogously to what is observed in the B","authors_text":"F. La Franca, P. Andreani, S. Cristiani, S.
