  The statistical test described by Wielen et al.(1994) is used to derive new
zero-points of ground-based Cepheid period-luminosity (PL) and
period-luminosity-colour (PLC) relations. Eleven relations are compared with
the Hipparcos data. Our results argue for a typical increase of the adopted
distance scale by about 8% +- 8%. Our zero-point for the PL relation of
Caldwell & Laney (1991) is in agreement with that of Feast & Catchpole (1997).
