Resumen:
A robust procedure for conditional testing the hypothesis of elliptical symmetry is presented. It also provides a specialized test of multivariate normality. We derive the asymptotic behaviour of the robust conditional testing procedure under the null hypothesis of multivariate normality and under an arbitrary elliptically symmetric distribution. Their influence function is also studied. A simulation study allows us to compare the behaviour of the classical and robust test, under different contamination schemes.
