  In order to study if the anisotropy of the spacetime may induce differences
in the cosmic shear or in deceleration parameter we investigate in Bianchi I
Universe the most general expression for the cosmic shear and we study the
connections between deceleration parameter and cosmic shear. We also consider a
shear parametric approach to measure the transition from decelerating to an
accelerating Universe. We also study the connection between jerk parameter and
ellipsoidal Universe.
