A parametric reconstruction of the cosmological jerk from diverse
  observational data sets
  A parametric reconstruction of the jerk parameter, the third order derivative
of the scale factor expressed in a dimensionless way, has been discussed.
Observational constraints on the model parameters have been obtained by Maximum
Likelihood Analysis of the models using Supernova Distance Modulus data (SNe),
Observational Hubble Data (OHD), Baryon Acoustic Oscillation (BAO) data and CMB
shift parameter data (CMBShift). The present value of the jerk parameter has
been kept open to start with, but the plots of various cosmological parameter
like deceleration parameter $q(z)$, jerk parameter $j(z)$, dark energy equation
of state parameter $w_{DE}(z)$ indicate that the reconstructed models are very
close to a $\Lambda$CDM model with a slight inclination towards a non-phantom
behaviour of the evolution.
