The interference model is widely used in block experiments, where a
treatment applied to one plot also affects its neighbors. This paper examines two
proportional interference models, where the neighbor effects are proportional to the
direct treatment effect. These models have the advantage of requiring fewer parameters
to estimate but face challenges due to the nonlinearity of the estimates. Although
conceptually simple, their technical implementation is somewhat more complex.
In this paper, we examine two-sided and one-sided proportional interference models
and transform their nonlinear nature into a more manageable form by assuming that
the proportionality constants are known. Our findings provide a closed-form analytical
solution for optimal designs under proportional interference models.
