Constraints on kinematic models from the latest observational data
  Kinematical models are constrained by the latest observational data from
geometry-distance measurements, which include 557 type Ia supernovae (SNIa)
Union2 data and 15 observational Hubble data. Considering two parameterized
deceleration parameter, the values of current deceleration parameter $q_{0}$,
jerk parameter $j_{0}$ and transition redshift $z_{T}$, are obtained.
Furthermore, we show the departures for two parameterized kinematical models
from $\Lambda$CDM model according to the evolutions of jerk parameter $j(z)$.
Also, it is shown that the constraint on jerk parameter $j(z)$ is weak by the
current geometrical observed data.
