Gravitational lensing will cause a dispersion in the Hubble diagram for high redshift sources. This effectwill introduce a bias in the cosmological parameter determination using the distance-redshift relation for Type Iasupernovae. In this note we show how one can diagnose and correct for this bias when doing precision cosmologywith supernovae.Key words. Gravitational lensing – cosmological parameters – Methods: statistical
