The smooth spin-down of young pulsars is perturbed by two non-deterministic phenomenon, glitches, and timing noise. Although the timing noise provides insights into nuclear and plasma physics at extreme densities, it acts as a barrier to high-precision pulsar timing experiments. An improved methodology based on the Bayesian inference is developed to simultaneously model the stochastic and deterministic parameters for a sample of 85 high-{dot}E radio pulsars observed for ∼10 yr with the 64-m Parkes radio telescope. Timing noise is known to be a red process and we develop a parametrization based on the red-noise amplitude (A_red) and spectral index (β). We measure the median A_red to be -10.4^+1.8_–1.7 yr^3/2 and β to be -5.2^+3.0_–3.8 and show that the strength of timing noise scales proportionally to ν¹|{dot}ν|^-0.6±0.1^, where ν is the spin frequency of the pulsar and {dot}ν is its spin-down rate. Finally, we measure significant braking indices for 19 pulsars and proper motions for 2 pulsars, and discuss the presence of periodic modulation in the arrival times of 5 pulsars.
