analysing an agricultural field experiment with observations that are positive
on a continuous scale or zero. Such data can be analysed using two-part models,
where the distribution is a mixture of a positive distribution and a Bernoulli
distribution. However, traditional two-part models do not include any
dependencies between the two parts of the model. Since the probability of zero
is anticipated to be high when the expected value of the positive part is low,
and the other way around, this article introduces dependency-extended two-part
models. In addition, these extensions allow for modelling the median instead of
the mean, which has advantages when distributions are skewed. The motivating
example is an incomplete block trial comparing ten treatments against weed.
Gamma and lognormal distributions were used for the positive response, although
any density on the support of real numbers can be accommodated. In a
cross-validation study, the proposed new models were compared with each other and
with a baseline model without dependencies. Model performance and sensitivity
to choice of priors were investigated through simulation. A dependency-extended
two-part model for the median of the lognormal distribution performed best with
regard to mean square error in prediction.</span></p></div></div>
