In an earlier paper, our classical models study included simulations to explain the variability
in coefficients of determination (R2) between fineness and maturity, micronaire and
fineness, and micronaire and maturity of cotton. Subsequently, we emphasized the
derivation and testing of three diagnostic models to enhance the R2 and provide information
about the analytical quality (accuracy) of the results. In this paper, the theory of biased
fineness and maturity measures is introduced and effects on the relationships with
micronaire are simulated. Error functions based on Lord's micronaire model are derived to
express biased results relative to the unbiased values. The simulations include three case
studies in order of increasing complexity: bias varies linearly with micronaire, bias is
nonlinear with micronaire, and random error is added to the bias. Classical and diagnostic
model plots of the simulated unbiased and biased data are presented in detail to readily
determine differences in the relationships.
