  Among the five pulsars with the most recorded rotational glitches, only PSR
J0534$+$2200 is found to have an autocorrelation between consecutive glitch
sizes which differs significantly from zero (Spearman correlation coefficient
$\rho=-0.46$, p-value $=0.046$). No statistically compelling autocorrelations
between consecutive waiting times are found. The autocorrelation observations
are interpreted within the framework of a predictive meta-model describing
stress-release in terms of a state-dependent Poisson process. Specific
combinations of size and waiting time autocorrelations are identified,
alongside combinations of cross-correlations and size and waiting time
distributions, that are allowed or excluded within the meta-model. For example,
future observations of any "quasiperiodic" glitching pulsar, such as PSR
J0537$-$6910, should not reveal a positive waiting time autocorrelation. The
implications for microphysical models of the stress-release process driving
pulsar glitches are discussed briefly.
